Comet Lulin visible under worst condition
I carried my 11x70 to the top of our dormitory at around 14:50 UT. The sky condition has improved significantly compare to that of the morning (overcast), but it's still mostly cloudy, with a few bright stars occasionary visible in the cloud gaps, I estimated the LM to be around +1.0 at that moment, one of the worst observing nights I have ever experienced. However I still manage to spot the comet. At around 15:05 UT, a clear region was passing over the Lulin region, so I point my binocular to the southeast direction of Saturn. I move the observing field a little bit and feel that there is a small "cloud" near a curve lined by four stars. A very clear gap was just passing the region and I was able to confirm its existances. A 7.46 mag. star coded TYC 267-888-1 was also visible at those seconds, so I estimated the surface brightness of the comet to be around 7.5 mag, with a diameter up to around 20'. The cloud came again after less than half a minute and was increasing again, after waiting for five minutes I packed my binocular and went downstairs.
I'm very pleased to find the comet is such a bad condition, but I think experiences are required under such a condition. Also I need to point out that the brightness estimation is far from reliable since the sky condition is far from satisfying.
I should have wait for more time but today I'm very tired. I think I must go to bed now or I may catch a cold. Good luck to you all!
Update: I just receive a fresh image from Lulin Observatory, taken by the Lulin 10-cm f/8 refractor with U9000 CCD last night (300s x 5 combined). The comet looks really gorgeous! Note its newly-developed beautiful dust tail! After earning their permission to publicaze the image on my blog, I'm showing it here. Well, I just bound up my hair for a few hours last night and the comet soon made a response? (the comet looks very different now comparing the images prior to Feb. 22, you may browse spaceweather.com for a comparasion) Bravo, fantastic. I'll depart soon for Gaocun Village, a remote site about 150 kilometers from Guangzhou which is one of the bases of our Guangdong Southern Cross Star Association, for a good view of the comet. Stay tuned for updates.

Revised on 2009 March 12. With the help from Sisi Chen, I finally managed to make a "Lulin-style" hair before I cut it off -- see above. I wish to thank Sisi for her patient and help. Sisi is also a fan of astronomy, and she had been well possible to study astronomy in Nanking

It has been cloudy since Feb. 26, meanwhile I spent nearly 12 hours each day on bed to make myself recover faster from bad cold, I'm feeling much better now. Over the next weekend I'll fly to Beijing and Tianjin, meeting friends, and giving a talk about Comet Lulin and the total solar eclipse at Peking University, I'll also attend the

After the Lulin observing compaign on Feb. 24/25, my tireness of long travel, preparation of the new term operning and many other things stacked and made my bad cold intensified into the worst bad cold I have ever experienced in past ten years. I feel sleepy everywhere, unable to recall something quickly, even unaware of what

I departed with a few friends from Guangzhou for Gaocun Village at around 22:30, Heng Zhou drove the car. It's our Guangdong Southern Cross Star Association which held the party, and there is only one topic -- Comet Lulin. It was prefectably clear all the way down, but according to the messages from those friends who arrived

It has been quite a while since my last update about Lulin. Sorry, guys, I learn that many of you keep visiting my blog to see what's up with Lulin's boyfriend. Actually, I was on travel from Feb. 2 to 21, that's in the course of my "five-ring" project. I plan to visit China's every corner by

Today is my last day at Nanjing, I visited Ming Tomb, Dr. Sun Yat-sen's Mausoleum, Gate of China, Nanjing Wall, etc. These places are great (actually, you may have seen the recently-updated photos here, they were all taken during my country-cross travel). But the biggest surprise is made by Liaoshan and Yunxi, sending me such a

Sorry for lacking of updates on Lulin, I haven't many stories to tell as the comet speaks itself (herself), what's more, I'm now on a cross-country travel and is always on mobile, so I can't write much. If any of you happens to be at a YHA around Shanghai now, please let me know and we

I drag myself out of bed again at 4:30 a.m. It's another very clear night, with limiting magnitude around 5.4 (using IMO method -- but this do not mean that tonight is better than last night, since last night I had to use a not-well located reference field as the cirrus block the favourite one).

As Comet Lulin is now approaching the Earth, the questions such as "how is your comet" or "did you take look at your comet" frequently fly into my ears. When replying these questions, I'd love to refer the comet as "my girl", and a standard reply is "no, I haven't date with her since last

[Images Removed] A total of nine images of Comet Lulin were taken by the Lulin 0.41-m reflector over the night of Jan. 5, and I used every of them to process three impressive images as you have seen above. The first one is a color image, combined from one Blue-band image, one Visual-band image and seven
