NASA News
A green comet may be visible to the naked eye early on the morning of February 24, 2009.
"To see Comet Lulin with your own eyes, set your alarm for 3 am. The comet rises a few hours before the sun and may be found about 1/3rd of the way up the southern sky before dawn. "
"Lulin's green color comes from the gases that make up its Jupiter-sized atmosphere. Jets spewing from the comet's nucleus contain cyanogen (CN: a poisonous gas found in many comets) and diatomic carbon (C2). Both substances glow green when illuminated by sunlight in the near-vacuum of space."
They seem unsure of what might happen though, as the comet has never been to the inner solar system nor experienced large amounts of sunlight. |

I'm not really equipped for good astrophotography. The S3 Pro is pretty old now, and is not the best for noise at iso 800. I don't have a motor drive tripod either, so shooting at 15 or 20 sec makes trails. Maybe in a couple of days we will get a clear night here and I will be able to get the double tail if it grows back.

I'm hoping this comment was in jest. Your tiny image may be sharper, but it just looks like a green paint brush stroke made in MSPaint. Waddy's gives sky context and feels more real.

Awesome, I wish the weather had permitted viewing of this for me. |

There was a pretty good photo of it in the local newspaper the other day. It was taken just north of here. That same paper published a diagram of where it would be at 11pm each night before March 3. Generally, it was passing by Jupiter. |

Near Saturn, I think, not Jupiter. There was mention of it in the post/article about the the simultaneous transit of four of Saturn's moons the other day. |

Ah, you're probably right. I was reading it in Japanese and it's not always easy to remember which planet is which. Anyway, it's the bright one at the moment. ;-) |

LOL... uhm... I'm guessing that you didn't look at the date on his original post(?).
eta: or the fact that it said "preview" of the comet :O)

Article on quadruple transit of Saturn's moons with nice picture(s). Exerpt:

Editor's note: To find Saturn on Feb. 24th, look southwest before sunrise. The planet is easy to see shining like a golden first-magnitude star in the constellation Leo: sky map. By cosmic coincidence, Feb. 24th is also the date Comet Lulin makes its closest approach to Earth--and the comet is right beside Saturn! Using a small telescope you can catch a comet, a ringed planet and a quadruple transit; it's a nice way to begin the day. |
I recommend signing up for the newsletter -- usually 1-4 interesting emails/week. |

It was made in Photoshop, not MS Paint, thank you very much! |

I got a warm, soapy cloth here for Smurfguy :-)

Anyone else got any shots at this event?
In the evening at about an hour after sunset, it is generally east south east, and below Saturn, which is the 2nd brightest object in that area. There are a couple of bright stars above Saturn, and it is near one of those tonight.
