Green comet approaches Earth

From the article:

Comet Lulin is a green beauty that could become visible to the naked eye any day now.
...
The comet makes its closest approach to Earth (0.41 AU) February 24, 2009. Current estimates peg the maximum brightness at 4th or 5th magnitude, which means dark country skies would be required to see it. No one can say for sure, however, because this appears to be Lulin's first visit to the inner solar system and its first exposure to intense sunlight. Surprises are possible.
...
To see Comet Lulin with your eyes, set your alarm for 3 a.m. The comet rises a few hours before the Sun and may be found about one-third of the way up the southern sky before dawn. Here are some dates when it is especially easy to find:
...
February 24th: Closest approach! On this special morning, Lulin will lay just a few degrees from Saturn in the constellation Leo. Saturn is obvious to the unaided eye, and Lulin could be as well. If this doesn't draw you out of bed, nothing will.

The comet should be worth a look now, for those lucky enough to have clear skies.

NASA's Swift satellite has taken some pix in ultraviolet and X-ray light: NASA's Swift Spies Comet Lulin, though they've made it look a pretty pink and purple. APOD Feb 21 also has a nice pic.

APOD Feb 7 shows the comet in its true green colour.
