A Lulin-style hair before hair cut
Mar 5th
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 University -- but for some coincidence she came to Sun Yat-sen University and study meteorology as me.
Today I went to the barber's and cut my hair very short. Let's see how Lulin will response this time! Before updates on Lulin's appearance, let's see some nice photos from Lulin and others.
This very nice photo is taken by Michael Pagitz with a GRAS (Global Rent-a-scope) telescope, used with permission. Michael is a long term user of 7Timer! service (http://7timer.y234.cn) and I'm really happy to see his nice Lulin image!
And finally I took some Lulin images with the 0.41-m reflector (the one which found the comet) during the course of Lulin Sky Survey, and confirmed that I have to the right to publish them on my blog this time (but please don't re-post these images on your sites). The animation above show a major burst during late Feb. 25, the duration of this animation is about 1-hour (around 15-16h UT).

The one above is taken on Feb. 28 with LRGB combined, the total exposure time is about 170 minutes. There are other images below you may have a look. According to the latest reports, the comet is still visible to naked-eye observers at magnitude of about 5.5.
