己丑七夕
當日賦於交趾越州。尤劣甚，未畢，待正。暫及於此。
玉魄西欹藏海氣，
疏雲微渡接星河。
迢迢凝望兩無語，
曲歇七襄離恨多。

爺爺永遠地走了……己丑年六月初八的晚上，爺爺就那麼安詳地去了，一句話也沒留下，睡得很香，可就是再也喚不起了。爺爺長眠在屋後的小山的高崗上，有一片長不大的松林，遍地的桃金娘，還有許多淡黃的不知名的小野花。山下是略微熱鬧的城鎮，東邊的小溪在緩緩流淌著。遠方是綿延的群山，東北六萬大山的餘脉顯得格外高峻。
就這樣驀然撒手，就這樣一去不回頭。向來情深厚，如今許多往事在心頭。山悠悠，水悠悠，拂面清風，吹不散心中點點愁……
那些天老家的天空顯得格外的藍，陽光很刺眼，白雲去悠悠。偶爾還會下幾陣雨，瀟瀟地打在台灣相思的葉子上，打在了翠綠的竹葉上，然後一滴一滴地沾濕了磚紅色的泥土……那恐是老天爺的淚水？或許一個甲子後，我也會化成白骨，或在烈火中紛飛，或在地底腐爛……但這無關緊要，只要在有生之年，吾輩盡行孝悌，萬不可在親人離開後方懊悔。
僅以一小詩悼念爺爺，天國之路一路走好！
殘陽淪合浦，葉落逐風飛。
月昃南流水，雲空鶴獨歸。

祭盧溝英魂
民國卅六年七月七日，倭寇無恥，挑起盧溝橋事變。我二十九軍寧為戰死鬼，不做亾國奴。遂奮起抵抗。拋頭顱，灑熱血。浩氣永存，可謌可泣！爾來七十有一載矣。吾乃中華子孫，焉能忘先烈之悲壯，國家之恥辱。遂為詩以緬懷抗日殉國將士。
幽燕戰火漫無端，義士英豪衛故巒。
暗影流光雄膽壯，霜鋒閃耀寇心寒。
橋獅有怨銘石破，曉月無聲照壘殘。
歲月乾坤存碧血，中華同祭淚汍瀾。

前幾日天氣極好，市區目視極限星等竟至4等！看COBS無甚彗星C/2007 W1之北半球觀測報告，有的也稱角度很低，故想當然地以為此地亦不可為——光害甚重而豈可觀之。今日方查Carte du Ciel，大呼後悔。彗星觀測角度甚佳——皆因本地緯度較低。再看天氣，悲哀——即將轉壞……复犯想當然之誤…… 6/29/2008
戊子年五月初十，與友人同遊長洲中心湖。依林傍湖，閑庭野徑。隱隱之畔，頗得山人之樂。有感而發，故戲作詩二。
（一）
五月風光勝，偕朋步隱池。
幽鶯空恰恰，深柳自依依。
閒雨滋青草，微颸撫碧漪。
流連隨意趣，此樂竟何極！
（二）
荷葉田田一色空，傍沙岸鶩眼迷濃。
南風忽雨聲萬點，驚卻修靈入蘆叢。
生澀言語，不知所言。 6/28/2008
高考昨日成績出爐，因總分而言不可說砸，雖並不理想——離理想者尚差甚遠。可科科而論，有所喜，亦有所不解。
所謂喜，在於物理。物理乃我歷史第二高分，其分數未出乎我之意料。不過萬萬沒想到我是全級最高……本想著本班會有好幾個上140的，結果……
所謂不解，在於語、數二科。語文不知為何連班平均分都未上，高三以來首次……數學遠低於自己預想達10分，竟才剛剛平均分……不明不明……
有些暈，似乎被某些人用金剛琢砸了一下……說傷心倒也沒有，畢竟犯不著向應試低頭。就是對語文及數學感到有些難以置信……南大天文系……應該沒了……
還好，這個假期我計劃得挺充實的。大把的事情等著我去完成。或許之中有些是特別奇妙的，也不愧是充滿希望的…… 7/29/2007 再有感於國內彗星觀測
好了，終於又有亮彗星啦！ 的確，C/2006 VZ13 (LINEAR) 是個亮目標。不錯啊，上了7等！ 嗯……比4月份的C/2007 E2 (Lovejoy) 還亮， 是自C/2006 P1以來最亮的彗星了。 “7等啊……還是暗了點……看看算了，拍拍罷！”
那好，既然暗了些，且說C/2006 P1罷。
C/2006 P1誠然是個好傢伙啊！你看，12月底增到3等，一月初突破0等，再到中旬超過金星亮度——白晝可見，多壯觀啊！ 國內同行不錯，努力拼搏，終成正果。這不，不少人不看到了這顆40年來最亮的大彗星嗎？一月初，國內關於06 P1的照片紛紛而至，賞者皆嘆焉。真是國內同好的拍攝水平又上了一個新台階啊，如此難度都能拿下，鼓掌鼓掌！！“這張照片太漂亮了，XX辛苦了~~難得一見的大彗星啊！！！！”既然承認難得一見了吧？那麼好，也就等同於少見了吧？那好，也就是研究得少而科學價值豐厚了吧？“關我們什麼事啊？？”——既然我們難以親自下廚，難道連幫助人家增料也不行嗎？？越是少見，觀測數據的科學意義就越大，難道連這種也不懂嗎？？“我們不有照片嗎？”——對，欣賞價值極高啊，攝影者水平高超，了不起！有科學意義嗎？？其科學價值遠遠小於欣賞價值！說白了，不過就是一張片子，先悶頭欣賞幾個月，自嘆自的，然後讓他人讚嘆一番，最後跌入塵封的世界中！數數ICQ的Recent Magnitude Estimates的一月份報告，共計162份，由於20日以後，彗星亮度下降，對於普遍處於糟糕空氣質量下的觀測者以基本無法白日觀測，故元旦始自19日，共計127份，而國人的報告僅有二人三份！！另外來自東北的一位觀測者也有數份標準的觀測報告。其餘的，還有，當然有觀測報告啦，你看，一堆文字，抒情佳篇，見不到一點關於彗星的亮度等科學信息。照片嘛，那可就多了！ 堂堂中華，堂堂中華！！ 以前談到觀測彗星要做彗星觀測報告這種最基本的，大傢伙總說，哎，太暗了，才X等，太難了——這次來個亮的，40年來最亮的，“哎，太難得了，拍攝更重要啊！”
大傢伙總愛說，什麼儀器不比國外的先進。依我看來，不過托詞，阿Q同志的精神勝利法而已，自我麻痺，自覺沉墮！根本上，就是素質問題！大傢伙熱情高漲，“國內高漲天文熱”，若是有敢潑冷水者，必糟“群眾”唾罵。 無所謂，說實情不是甜蜜之語，既然我敢以訴之，就不怕“群眾”唾罵。我倒想看看精神勝利法能用到何世紀何年何月。
不好意思，給大家潑了盆冷水。 嗚嗚……有違“和諧社會”建設。大家活得自在，我算哪門子球蛋？？敢潑冷水！！自討苦吃！！
於是烏雲將我籠罩，我無意中學會了悟空師父的縮骨法，被世人按做了小小黑子，埋入塵中，則再無雜音。果然，四處唱起了《和諧之音》—— 7/21/2007
電腦崩盤，藉他人之一用。13、14日終於在購書中心發現並買到了我等了3年之久的著名人物Sir Thomas Heath的著名書籍：《The Works of Archimedes》和《A History of Greek Mathematics》！！！激動了許久~~目前正刻苦研究著……真是相當佩服古希臘人的智慧……例如Archimedes求抛物線弓形面積方法之一是利用杠杆原理——數學問題物理化——雖然我老早就知道了，但是最近又被“洗禮”一番……現在我依然在苦等著Heath爵士的另二名作《Aristarchus of Samos》及《Greek Astronomy》……
另外7月8日淩晨00：30~03：00對彗星C/2006 VZ13 (LINEAR)進行了觀測並繪圖。結果如下：
OBS-V C/2006 VZ13 (LINEAR):
2007 July 07.75, ml=7.6, Dia.=6’, DC=4... (10.0cm-refractor, f/7, 28x; W.-t. Xu, Guangzhou; City light pollution but clear sky;) 6/25/2007
副高帶漸漸東移，雲量增多，所以抓緊時間進行觀測。由於考慮到城市光害過重，遂周六往郊區觀測點，目標是C/2006 VZ13和新星V390 Normae。天空透明度差，有月光干擾，主要是中層雲影響觀測；南方嚴重受公路光害影響，北部及東北條件相當不錯。24日0時許開始觀測V390 Nor，受雲及光害影響未果，視場中該區域極限星等僅爲8.5等，而從AAVSO資料庫中得知該新星亮度在10.3等上下。24日23時許再次找尋，不過已經回到了市區，陣風風力較大，透明度比淩晨有所提高，但礙於光害，極限星等也只有9等多，若仍在郊區可能有戲。24日淩晨本想觀測C/2006 VZ13，在仙王座，亮度不錯，9.5等，就是高度較低。然而受中層雲影響，觀測失敗。 5/29/2007
Terry Lovejoy運氣真好，幾年的努力沒白費，是辛勞換來的，運氣固有，可技術更高！5月26日他再次發現一可疑彗星，依然是偏綠，新西蘭的John Drummund發現目標彗發直徑約1′上下，目前E12已經確認了該目標，亮度在13等上下。仍爲NEO確認頁面的目標，估計明後天就可以正式確認，獲得編號了。祝賀！

SWAN中的彗星185P/Petriew已經變得相當明顯，2月22日將一系列最近發佈的圖片下了之後，迅速發現了該目標，開始以爲是SWAN圖片因太陽移動而造成的假像，後來發現路徑有點彎曲，隨即加入我自己的SWAN可疑列表，後來查了Tracking，發現可能是185P，但由於謹慎起見，未刪之。今天受到Rob在sohohunter上發佈的郵件，的確是185P。這9個月來對SWAN的努力還挺有收效，呵呵，慢慢來，這可不比SOHO的LASCO視場。
現在目前這顆彗星在12等上下。但是與太陽的角距有點可憐。本來挺想試試，但是這逼近極限的傢夥的條件如此惡劣，恐怕無望…… 2/25/2007
很久未至此一遊了，主要工夫都花在了本人新建的主頁Homepage von Wentao Xu上了，歡迎各位友人踩個印，多多提建議。以後這裏都儘是弄些Gemischem，觀測日記都會轉到本人主頁上了，所以以後此處中文篇章就占絕大多數了。
春節在外婆家過的，儘是陰雨天，讓人挺心煩的。還好，22日晚上開始放晴，23日淩晨持續，結果幸運地抓到了新星V1280 SCO，然而就在這個時候，又是日本的中村祐二氏和桜井幸夫再次分別獨立發現了另一顆近9等的新星V1281 SCO，位置與1280十分相近，只差了3度而已！！要是當時觀測區域擴大些，或許再做完記錄後能夠發現異樣——“獨立發現”……這當然是玩笑，我現在能觀測到別人的發現已經相當不錯了，還圖什麽發現？？自己還得要經歷大把大把的磨練，才能“成精”。首先現在自己心態就有很大問題，調整倒急不來，慢慢來吧——
我越來越發現現在國內有至少95%的 “天文愛好者”就是攝影而已，高手是挺多，可是盡拍照片，質量再好，“精華”再多，反正我覺得沒有更多價值……前不久的2007年白日大彗星P1，多難得的機會，好些人曆盡千心萬苦，終於拿了下來——拍到了，“興奮啊！！！”，“照片真漂亮啊——！”……有用嗎？沒有觀測資料說話，說到底除了美的欣賞，增加點拍攝經驗，我實在想不到其他一丁點的價值。國內成功觀測到P1的人我就各大論壇上看，不下15人，而有彗星觀測資料的就3人：葉泉志，張學軍還有我本人。這實在讓我想到X.-M. Zhou老師在世時發表的關於2001獅子座流星雨國人的表現那篇文章……有人會說，國外不也如此嗎？看看如此多的網站，圖片多漂亮啊！個個是精華！“哇——”君不見cometobs多少資料，很多是一些照片的作者；君不見Comets-ml多少資料，同樣很多是一些照片的作者；君不見ICQ的Recent Comets Estimates，多少資料！！同樣還是很多照片的作者。國內——對比對比吧！
反正這是我的地盤，發發感慨，頂多遭來幾篇攻擊，算不上什麽。自己“多餘”，操操心，國內圈內形勢“並無好轉”，國人現在喜歡用精神勝利法，而且是濫用，爲自己的行爲開脫辯解。還是胡改一句元曲：去了由他！
既然是Gemisch，亂點無所謂，想到啥說啥，不是作文，不管太多了。說回春節，也出了些樂事。頭一件是年三十晚上睡覺，舅舅挂蚊帳弄了老半天，“汗又濕了身”，正想美美地鑽進去，呀，挂反了！床靠著牆，蚊帳門跑到了牆那邊……第二見是年初二外公到水聲下村喂狗，結果被狗鎖在屋裏邊，出不去——鑰匙插在外邊，自動反鎖……最後還是我表哥解的圍。這事把我一家人弄得哭笑不得。
寒假裏又有些電視臺在播西遊記。西遊記，四大名著裏本人最喜歡的就是它了。電視舊版本的我也是非常喜歡。以前是看了又看，每次看感覺都不相同。這幾年時間少了，只好一邊搞自己的東西一邊看電視舊版的。還是那樣，體會到的東西又不同了。所以我是百看不厭，實在是愛到了極點。舊版的雖說電腦特技遠遠趕不上新版，但是我覺得舊版的味道更濃，演員的化妝、動作，以及環境等都比新版的好。我還十分喜歡舊版裏的歌曲，例如第十三集《三打白骨精》最後那首曲子——我不喜歡現在雜七雜八的流行音樂，要問我什麽歌星，我能答出二成就很了不得了，故很多人把我看成異類。雖然歌詞記不得，但喜歡沒人時哼著唱，反正自得其樂，沈醉其中。以前本人還時時模仿六小齡童演的孫悟空的動作，挺多人說蠻像的，日後再拍西遊記時就找我~~~妝都不用化太多，長得像。
最後扯叉足球，剛剛看完了拜仁的比賽，真的讓我眼前一亮——很久沒看到拜仁如此酣暢的進攻，如此強烈的求勝欲望。自從看完歐冠皇馬主場3-2擊敗拜仁那場比賽後，感覺拜仁開始有了希望。然而陰影仍在——後防令人擔憂。尤其是今天對沃爾夫斯堡，雖然2-1贏了，但是比賽過程中沃堡幾乎每一次進攻都對拜仁造成了威脅，只是今天運氣還不錯，加上卡恩也有狀態，才讓人進了一球。比賽完了才終於放下心來。期待不久的歐冠16強次回合比賽拜仁能夠力克皇馬，殺入8強。However，我很沒底……
就扯這些吧。看看也真夠雜的。

OBS-V: C/2006 M4 (SWAN) & C/2006 L1 (Garradd)
Sunday, Dec 10, 2006
C/2006 M4 (SWAN) :
A strong cold front swept here swiftly, which led to quite a lot of rains. The temperature fell to 14℃ in nights. However, the minimum temperature was 19℃ some times ago. It gradually turned clear on morning of Dec 10. The transparency was extremely clear so I decided to make observations of some bright comets in my grandparents’ home.
I started my observation at about 10: 35 UT. The first target was comet C/2006 M4 (SWAN) that I hadn’t seen for long. I easily pointed to the position where the comet was using a rough stars field drew by myself through the finder. To my surprise, I could see the stars of over magnitude of 8th, which was still rare just in the suburb here. I observed through the main telescope then. The field contained a large number of faint stars. However, I couldn’t see anything like a diffuse comet. I kept on observing concentrated, finding something extremely faint in the predicted position of the comet. I doubted myself, regarding it as my phantom, for it appeared at times. I still kept observing and decided to make a sketch of the field to prove my result next day. It took me long to finish all of these. What’s more, measuring its magnitude and diameter was really hard under the slight-light-pollution circumstances. I doubted myself all the time during the observation for I didn’t catch its motion. I told myself it was just my phantom again and again. That’s it. However, after I had checked the electronic skymap, I was quite sure about it because that was just the right position for the comet. I was successfully finding this fading out object again.
Here comes my measurement:
Comet C/2006 M4 (SWAN)

2006M4 2006 12 10.47 S[ 9.2 TJ 10.0R 7 28 5 2 ICQ XX XUxx
PS: Extremely clear sky. Slight light pollution in this direction. Barely seen. Hard to measure its magnitude.
I stopped my observation of comet C/2006 M4 at about 12: 15 UT.
Gap-time:
The constellations of winter was getting higher and higher. Pleiades was easily seen high in the evening sky. Since I had finished the observation of C/2006 M4, I decided to have a good look at the clusters and nebulae. I firstly pointed to NGC 1778 in Auriga. Then NGC 1857, M38, M36, NGC 1893, NGC 1857, M42, M43, etc. Not had brought any other sketch books except the ones of specializing in comets, I didn’t do any sketches of these objects.
C/2006 L1 (Garradd)
I started my observation of C/2006 L1 (Garradd) at about 12: 25 UT. It was almost on the borderline of Auriga and Lynx. The condition of this comet was much better than the one of comet C/2006 M4 that nearly no light pollution towards NE and N. The sky was rarely and terrific dark under this circumstances. More faint stars could be seen through the telescope, whose magnitude could nearly reach to 11.8. I almost immediately detected that the star TYC3391-02440-1 of 11.33m had a very faint and diffuse “nebula”. As I knew, the weakly condensed comet now was just in this area according to myself-drawing sky chart. However, when starting to observe it systemically, I could not see anything except the fix stars. Resting for a while and observing again, I got it and lost it soon as before. I made every effort to observe in my field but nothing has changed much. Although I doubted myself again, I planned to sketch it. About an hour later, I “felt” that the diffuse object had moved a bit, which suggested it was a real object in the sky. I measured its size and magnitude and something necessary. My measurements are offered below:

PS: Extremely clear sky. Easier seen.
I hurriedly finished my observation there at about 14: 20 UT because I had to go to school next day. After checking the track of comet C/2006 L1 next day, I was quite self-confident. That was my second harvest on the day.
I took me about 3 hours and 35 minutes totally to observe comets. The total time of specially observing comets is about 43h05m up to date. I’ll clear up my all observations before including observing sun, planets, asteroids and deepsky when I’ve got enough time. That’ll be a huge mission, I think. 11/11/2006
OBS-V: C/2006 M4 (SWAN)
OCT 29, 2006
The sky was much clearer than a few days ago. It happened to be a weekend so that I planned to go on with my observation of the comet C/2006 M4 (SWAN) in my grandma’s home where lies in the northeastern suburb. So I did.
The sky was almost dark though a crescent still hung in the low sky. However, the sky near the western horizon was hazy because the road not far from my spot was under re-construction. But it didn’t matter much. A not-very-bright light was on that influenced my searching a bit as well.
It was about a quarter past ten (UT) that I started my observation. The position of the comet was very easy found as well as I could see it exactly through the finder, which formed a giant difference between the one did in the city and in the suburb. I caught the sight of the bright comet through the main telescope immediately. The strong condensation and the large size of its diameter gave me a deep impression.
I made two sketches and measured some data of it. Here comes the measurement:
Comet C/2006 M4 (SWAN)
2006 Oct. 29.47UT, ml=5.0, Dia.=11', DC=7.5, 10.0cm-refractor, f/7, (28X/70X)
PS: I observed in the northern suburb and sky was much darker, however, an avenue not far from my observational spot is under construction so that the lower sky was influenced by the dust. In spite of these, the comet was very easy to be seen and the coma was really large.
I stopped me observation at about twelve o’ clock that was it took me 1 hour and forty-five minutes to complete my whole observation.
I had to take the agricultural courses in Sihui, Zhaoqing from Oct 30 to Nov 3. It was really hard to squeeze the free time out but finally I came with an idea was that doing my observations of the comet C/2006 M4 (SWAN) after finishing my bathing. So I did and it really helped a lot during these days. The only equipment with me there was my militarian binoculars 15x50.
OCT 30, 2006
I settled in the yard at about two o’clock (UT). The sky was really blue there. I did my observation at once after finishing my bathing as I promised before. It was about 10: 15UT. Maybe I behaved a strange way that a guard followed me all the time. I was told that I could only walk within the square, which was shone by two very bright lights seriously. To make matters worse, the moon lit brightly as well. In spite of all of these, I could get to the position easily where the comet was. Soon I saw the comet in the field without much difficulty. It located between the stars ε and ζ Her. , next to 53 Her. It was more diffuse than several days ago and the brightness has faded down to about 5.3m according to my measurement. To my surprise, I can see the tail of 1-deg. in p.a. 35 deg. I finished my observation at about 11: 00 UT.
OCT 31, 2006
The sky turned to hazy in the evening and covered with thin clouds. Moonlight also influenced strongly. I observed the comet almost the same time. The three fix stars mentioned above were still easily seen but the comet was not. I spent quite a lot of time proving whether I caught it or not. Thanks to my effort, I caught the sight of the barely-seen comet finally. The magnitude of it was hard to measure under such poor condition. I could only say it was fainter than 5.3m. The observation was completed at about 10: 50 UT.
NOV 01, 2006
The moon was hidden from the clouds; no stars were seen that night. I didn’t do my observation.
NOV 02, 2006
The last night we had in that place. We beat the teacher there 3: 0 in a football match. I didn’t feel much pressure during the match. I began with my search at about 10: 20 UT. The sky turned fine again and the transparency was excellent today. However, the moon lit more strongly, which serious influenced my observation of my lovely comet. But I caught the comet without any difficulty. It was surprised that I could see its tail of 1.5-deg. in p.a. 35-deg.!!! Supposing that if no moonlight, it’ll be more enormous. My search was over at about 11: 10 UT.
NOV 05, 2006
Weekend again and I’ve already come back, so I did my observation of the comet C/2006 M4 (SWAN) in the northern suburb again. I started my observation at about 10: 15 UT. Firstly I could see the comet in the finder barely, but, when the extremely bright moon rose above the mountains in the east, a lot of faintest stars in the field were hidden. I could still catch details of the comet without too much hardness. Here comes the consequence of the observation this time:
C/2006 M4 (SWAN):
2006 Nov. 05.46 UT: m1=5.6, Dia.=7', DC=7, 10.0cm-refractor, f/7, 28x...
PS: Moonlight strongly interfered. Very clear sky! Though I didn't see the tail of

Go on with the Solwind files. I’ve tried to get hang of the skills for nearly a week. I downloaded the files in which some known Solwind comets were detected so that I can be familiar with it. Some images and animations are offered below.
Solwind-7 or C/1981 W1 discovered by R. Kracht in the images of 1981 Nov 20 on July 30, 2005.
More to come. 11/5/2006 IMAGING PROCESS (II)
Go on! But now are the Solwind images, not the SOHO files. Are there any potential Kreutz comets in those files? Yeah! But most of them were dug out by R. Kracht, who is one of the greatest German SOHO hunters in the world. Let me check them cautiously when I get hang of the skills. As I know, nobody in China has found any Solwind comets, which embarrass me “a bit”.
Ooh, here are the tiny “achievements”.

Okay, that's all I've for now. Uuh... I'm really tired since I got back. Well, goodnight! 11/4/2006

Well, it looks like we only have six or seven images showing
Tony's Kreutz. Oh well, better than nothing, I suppose...
Well done to Hua Su for spotting the first Meyer-group comet we
have had in a very long time! Fortunately we got plenty of images
for that one.

We should get our normal image quota back next week. Until then,
please keeping checking what few images we have for the return of
C/2002 R5 (there's a prize for its recovery...).

Wow! Many congratulations to Rob on his five-comet haul! It is
amazing for several reasons, including the first time we've had
five C3 comets in less than a day and the first time a comet
hunter has found five realtime comets in a day (four of which
were within less than an hour)!! Amazing stuff -- well done, Rob!
--
We're officially out of that horrible keyhole now so we should
have plenty of realtime data and almost all gaps filled 100%.
--
I hope you all like (or at least tolerate) that changes I have
made to the comet report form. Please let me know if you have
any problems with it. I have decided to keep a permanent link to
the old repotr form in case any of you have a preference. The
link can be found immediately beneath the current report form.

comet within a minute of each other and, as I can not be
certain on the timing of the sohohunter reports, they get
joint credit for the discovery.

There was a lot of "noise" on the reports page this time around.
90% of this can be eliminated if people would wait for a third
image before making a report. So please do so unless you are
convinced your object is real.
--
Bo's archive claim looks like it's real but it is just too faint
to be sure. It couldn't get good positions for it, either, so it
becomes X-Comet #55. Sorry, Bo! The archive report from Hua was
much better and I got six or seven good positions for it.
--
Congratulations to John on his fantastic Kreutz comet -- already
it is looking very nice indeed and must be at least a 4th mag
object. It wouldn't surprise me to see it saturate C2 a little.
Great find, John!

OBS-V: C/2006 M4 (SWAN)
The sky turned clear a few days ago. It was a good chance for me to observe the comet C/2006 M4 (SWAN), which has just experienced just an outburst on Oct 24, 2006.
Oct. 25, 2006
The sun shone brightly on the day, but cloudy in the evening. Failed certainly. It was my second failure of catching this comet. The first one was on Oct. 05.
Oct. 26, 2006
I had received a great number of reports that the comet C/2006 M4 experienced an outburst. Observation showed that it was 1.5m brighter than a few days ago. The sun shone brightly on the day. Having done some of my homework, I came back home at about 10: 15UT but I found that the sky was covered with thin clouds, especially the western and southern parts. I still tried to observe it but failed. It was my third failure.
Oct. 27, 2006
The sky seemed to be clearer than yesterday. The clouds happened to turn up again in the evening, but this time they moved away quickly and remained a beautiful blue sky. I moved my 10.0cm-refractor to the balcony swiftly when I got home. It was waste of time that searching the stars through the finder because of the heavy light pollution above the NW horizon. I swept the sky carefully and very soon, a comet-like object near an orange double-star burst into my field. I checked the software Carte du Ciel immediately and was excited to find that it really was the comet!
Though it was still slight hazy and bright background, I could see the coma and maybe its tail! It was fuzzy but condensed. An hour later, the comet C/2006 M4 (SWAN) seemed to have moved about 0.1 deg. towards east. Certainly I sketched it and measure its brightness and some others.
Here’s the report that I sent it to the CometObs:
Comet C/2006 M4 (SWAN)
2006 Oct. 27.46UT: ml=4.7, Dia.=9', DC=8, Tail: 0.5 deg.? PA=40 deg.
Refractor, D=100mm, f/7, 28x
PS: Severe light pollution above the NW horizon, so I can't measure the length of tail exactly, however, I can "feel" the direction of it.
Weather condition: slight hazy sky (much better than some days before).
I finished the observation since the comet was hidden by the bright background. The whole of it lasted about 1.5 h : from 10: 20UT to 11: 50UT.
Oct 28, 2006
The sky became a little hazier again. I started my hunting at about 10: 15UT and it took me long to sweep the double-star again because the poorer weather condition. Then I swept a few degrees towards east and found nothing except some of the faint stars in the field. Gradually I did find something fuzzy in the bottom. That was just the right position for the comet. I caught it again! It still remained its high condensation but the magnitude was down. Was it influenced by such kind of weather? I sketched and sent a report again.
Comet C/2006 M4 (SWAN)
2006 Oct. 28.46UT: ml=5.1, Dia.=6', DC=8, Refractor, D=100mm, f/7, 28x
PS: Severe light pollution above the NW horizon. The comet was hard to be seen though it was
bright!!
Weather condition: hazy sky (worse than yesterday).
I tried to write those visual reports in ICQ Format:

There are also a lot of improvements that I've to do. Oh, I forgot to tell you something today. The school's sports-meeting was just down today afternoon, however, our class got the last but three score eventually, which really upset me. But we're one of the key class in our grade, we can do our best in another way. Trust us, we can surely win sometime! Yesterday I saw Quanzhi who are now a freshman of Zhongshan University and we talked about almost everything during the time.
Well, that's it. I've to have a good sleep now for I've got a lot of homework to do tomorrow. Good-night! 9/28/2006 September 21, 3006 -- Quiet skies, stormy skies...
The past few weeks have been very unusual for SOHO comets. August was a shockingly quiet month for comets. In fact, we went from August 4th to September 2nd without a single comet discovery! That's one of the longest "dry spells" in recent years. The spell was eventually broken by a Meyer-group comet, found in C2 images by Hua Su. That comet was our first Meyer-group comet in nearly four months -- another unusually long comet-free period. And when Tony Hoffman spotted a Kreutz-group comet on September 11, so ended a 38-day period with no Kreutz-group comets -- yet another very uncharacteristically long "dry" time. But as we all know, when it has been dry for such a long time you have to expect a storm sooner or later, and two days ago we got ours...
It all began with a Kreutz group comet spotted by expert SOHO/LASCO (and SOHO/SWAN) comet hunter, Rob Matson, late at night on September 17th. Shortly after discovery, SOHO entered into a reasonably long data gap that lasted into most of the next day. During these data gaps, even though we do not have "real time" contact with the spacecraft, data from the instruments is recorded on board ready for downlinking at the next time of contact. I often give advice to comet hunters at times like this to watch the spacecraft contact times and await the influx of new data. Clearly, Rob was following this advice when the data began to flow because, in the space of 42 minutes and 14 seconds, he reported another four Kreutz comets in the LASCO C3 and C2 fields of view! By the time a few other comet hunters had rejoined the hunt, Rob had already cleared up. This was the first time that five Kreutz comets were visible in C3 in less than twenty-four hours, and certainly the first time a comet hunter has found five comets in such a short period. Congratulations, Rob!
Pictured opposite are three of the five aforementioned Kreutz comets (click for a larger image). The other two (SOHO-1189 and SOHO-1191) were a little way ahead of these, so I chose these three as a nicer image. You can see a short tail on SOHO-1190, and (even though it was the brightest of the five comets) a much shorter one on SOHO-1192. SOHO-1190 had no noticeable tail at all.

So, as you can see, SOHO is now up to 1,192 comet discoveries! PS:the original text is taken from here: Latest News and Information. 9/13/2006 Tony discovered a fairly bright Kreutz SOHO comet at 19:04:09UT, Sep 11. Certainly it became the first Kreutz one in the past 38 days. But unfortunately, it looks like we can see much of this bright comet because of the Keyhole. I measured some of the coordinates of the comet:

Uh... It's really a pity to get such few images to see this comet. I've heard that my favorite football team, the FC Bayern München 4 : 0 beated the Spartak Moscow. Let me have a small conguatulations, YEAH!!! 9/9/2006 Something happened tragically this week.
I sadly heard that the famous Crocodile Hunter, Irwin Steve had been killed by a stingray while he was captured on dramatic videotape near the Great Barrier Reef on 4 Sep. Steve was enthiusiasm for wildlife and have spent his entire life studying, working and living with the animails... His series 'The Crocodile Hunter' were well-known to people in the world. But now, he died... I can't see his new programs anymore. The only thing I can do now is to memorialize him forever.
I caught a cold so that I didn't observed the Lunar total eclipse yesterday. I'm feeling really uncomfortable now! The north wind has taken place of the south one, the temperature has decreased as well. These are my own feeling as I caught a cold though it is still very hot for other people. I hope I can get well as soon as possible, this kind of feeling is really sucks!! 9/2/2006 As Karl said, it was a very quiet August. All of the SOHO comets were discovered at the beginning of this month.
All the SOHO comets are listed below, the original writer is Karl, who is the specialist on confirming SOHO comets.

There wre really poor comets, I think. There hasn't been any SOHO comets for 28 days! I don't know when a new SOHO comet will come out, the only I can do is just waiting and waiting. 8/30/2006 I made an observation on the 1 Ceres though I had to go to school. The weather was really good, mightbe the pour has cleaned all the dust away.
It was easy to lock onto this bright asteroid. The method was also making good use of the ι, θ Piscis Austrini... It must be an very easy thing for those who are familiar to the sky. Certainly, I recorded my observation, this is my sketch(The circle means my field).
70×
I've observed Uranus as well, but I didn't do any record.
The whole observational time was from 17:50 UT~18:50 UT, weather: flouting clouds. Seeing: I Antoniadi. Transparency: AAAA 4/7. My telescope: refractor, D=100mm, F=700mm. My observational location: φ=+23°09′12″, λ=113°18′54″E. The Altitude of 1 Ceres: +27°40′~+18°46′. The Azimuth of 1 Ceres:+34°41′~+45°11′. C/2006 N3 (SOHO), detected on 14 July, 2006
Discovery story:
I discovered a bright Kreutz-II SOHO comet in the evening, July 14. I have to acknowledge that I found this comet very luckily.
Early in the evening, I've already downloaded the latest C3 images from the LASCO, and I've made a big mistake that I was chatting on the Böotes Forum instead of checking them at once. After that, I changed the images into b/w. I shifted them in order and immediately discovered a comet like object moving towards the sun. I was getting nervous as I might be later than other SOHO hunters. I already had four coordinates, however, I didn't report it because I did NOT want to make too much noise report.
I waited and waited, refreshed the comet report page again and again. It was too long for me!! Finally, the image of 1118UT came out! I turned the color and measured the position...Yeah! It was a real one! I reported it at once and there was nobody before me. I couldn't be too lucky!
