Multi-tails of Comet C/2007 N3 Lulin
[Image Removed]
Continuing my post on Jan. 2, one more image of Comet Lulin is hereby publicized. A total of five R-band images, taken by the 0.41-m Lulin reflector on Jan. 2/3, were aligned and combined to create this image, a "bold" dust tail (anti-tail) plus three medium-to-weak ion-tail can be seen with ease. "We are observing comet C/2007 N3 Lulin 'edge-on' with incredible fortune!" Michael Mattiazzo (by the way -- he is among the astronomers I had visited during my trip to Australia) remarks, as the orbital inclination of Comet Lulin is about 178 degrees -- virtually in the same orbital plane (but moving in the opposite direction) as the Earth. Benefically from this situation, the brightness of the comet will be enhanced since we are observing the comet and its dust tail "altogether". More materials will appeared on Yeiht (this site) when they are ready.

A Lulin-style hair before hair cut

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

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.

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
Lulin dating compaign: update on Jan. 31

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).
Second dating with Lulin

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

Hi Quanzhi!
I'm Timo Karhula, an amateur astronomer from Sweden. Congratulations on your comet discovery!
I observed it on Monday, 5 Dec. 5:50 UT, with my 18x50 Canon IS binoculars. I have not heard of anyone yet who has seen the comet as far north as me (latitude 60N)!
I will visit your beautiful country in July to see the total solar eclipse!
Clear Skies!

Hej Timo,
Nice to meet you and thanks for your congratulating. I had spotted the comet visually at 43N in August, now I'm looking forward to watch it naked-eye for the second time.
In July I may be at Shanghai for the eclipse, where will you go? Welcome to China! And I hope your trip will be a pleasant one. I had been Stockholm once for the International Astronomy Olympics (IAO) in the year 2003.
Clear skies,
Quanzhi
