A quick and dirty photo I took this evening of Comet Lovejoy. It’s a little lopsided and quite green. I downloaded a spectrum from the web for Comet Lovejoy. The spectrum shows a peak for CN (cyanide) compounds and a number of peaks for C2 (diatomic carbon) gas. The C2 gas gives the comet its green color. This comet has a fairly high gas/dust ratio.

Thanks, Dion. This comet is still pretty bright in the telescope. I never have seen it naked-eye. Dave

Thanks, Deb. Maybe we can go out viewing one of the next times I’m off. I’d like to look through a 15-inch scope. Dave On [Feb 16], at [Feb 16] 4:45 PM, Debbie wrote:
