Comet Lovejoy


A new comet discovered by a digital camera, Comet Lovejoy.
IAU Circular No. 8819 states -
COMET 2007 E2
Terry Lovejoy, Thornlands, Queensland, Australia, reports his discovery of a comet with a strong central condensation and a green extended 4' coma, with a slight extension to the southwest, on sixteen 90-s CCD images obtained on Mar. 15 with a Canon 350D camera (+ 200-mm f/2.8 lens); the coma diameter was given as 5' from his Mar. 16 frame (his positions below have estimated uncertainties of +/- 15"). At Lovejoy's request, J. Drummond (Gisborne, New Zealand, 0.41-m reflector) confirmed the comet visually at mag 9.5 (moderately condensed, coma diameter 2'.6, no tail).
