Lulin to reach her brightness maximum
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 complete five paths on the country, and this ring is the No. 2. This time I travel about 5,200 kilometers, while 312.7 kilometers of them were in hiking, I visited 16 places in those 20 days, and this trip is nicknamed "eastern minor ring" by myself.
Okay, enough chatter. The new term has begun so I back home and back to the campus, with my 11x70 binocular this time. I had once brought my 11x70 and even the 13-cm refractor to my dormitory, but they did not stay for long -- because our dormitory building is facing the girl's, so there had been some guys asking what could I see through the telescope when pointing it to... somewhere. "Oh well," I replied, "be aware that you will see many pores!" After all, I brought my telescopes home.
According to the most recent (in 24 hours) observations, Comet Lulin has brighten to about mag. 4.6-5.0, with a coma of 20'-30' (even as large as 50' in naked-eye reports) and a tail at a length at about 1-2 deg. Here at Guangzhou it's still cloudy, but I expect the sky to be partly clear tonight and mostly clear in Tuesday night. To let you know, I can't wait anymore to see the most beautiful Lulin!
Although there are no observations from the discoverer at this moment, I get something that might be interesting. After Dr. Tony Phillips' article at NASA, Lulin has got a new nickname, "The Green Comet". I love this name, not only because the fresh green fuzzy ball is lovely indeed, but also for another reason. Why does it looks green? Cyanogen and diatomic carbon count one; another reason is a Chinese language humor -- my family name is Ye ("叶", pronounce as "yeah"), and this means "leave" in Chinese, while Chi Sheng Lin's family name means "forest" ("林", combination of two "wood" charactor), both "Ye" and "Lin" relate to green color, so that may be one of the reasons why the comet looks green.
There are confusions about why Lulin has two opposited tails. I create a simple figure to explain this phenomena, see below.
Okay, so much for this. The sky is clearing, so I'm going out for a try. Stay tuned for update!
