Congratulations to Terry Lovejoy from Brisbane, Australia on his photographic survey discovery of a magnitude 9.5 comet in the deep southern sky! 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).

Terry Lovejoy of Thornlands, Queensland, Australia, has discovered a 9th-magnitude comet in the southern constellation Indus. In reporting the find to the Central Bureau for Astronomical Telegrams (CBAT), Lovejoy described the comet as having a green, 4' coma with a slight extension to the southwest. Its position on March 15.73 Universal Time was right ascension 20h 44.1m, declination -51 14' (equinox 2000.0), and it appears to be moving 0.55 per day north-northwestward, toward Alpha Indi.
