Comet Lulin's Path
02.27.2009  15:30


Here is an addition to the previous post that I wrote about the Comet Lulin.

From here on out
The following animation displays the path that Lulin will take over the next month and a half, from 2009/02/28 until 2009/04/17. It was the brightest the last few days, and will now dim.

Actually, the comet remains in much the same location in the sky (near the West foot of Gemini) for months after that. That is just due to how the orbits of Earth and the comet play out. Before long, the sun will move between the Earth and Lulin, and the green comet will be too dim to be seen by all but the most powerful telescopes by then. The animation also shows a couple other interesting combinations with the moon, such as Saturn near the moon on the morning of 2009/04/07, the comet on either side of the moon the mornings of March 7th and 8th, and the moon passing closeby the comet the morning of April 2nd.

The NASA Swift spacecraft captured the following image in ultraviolet and X-ray wavelengths on January 28, 2009.
