From Wikipedia: Comet Hartley 2, officially designated 103P/Hartley, is a small periodic comet with an orbital period of 6.46 years. It was discovered by Malcolm Hartley in 1986 at the Schmidt Telescope Unit in Siding Spring, Australia. Its diameter is estimated to be 1.2 to 1.6 km. It will be the subject of a flyby by the Deep Impact spacecraft on November 4, 2010, with a closest approach of 700 kilometers. This is part of the EPOXI mission.
And here’s NASA’s view of it from the EPOXI mission.

Was it really this green?
Some time in 1997?
A blast from the past. Found this scan of a picture I took of Hale-Bopp from the Isle of Arran. Don’t have much info about it but it was taken with a 35mm Praktica and a 135mm lens.
Trees and light pollution are obviously an issue but not too bad. An impressive comet!
