C/2013 R1/ ＜ラヴジョイ 彗星 ＞(2013)

The discovery of C/2013 R1 Lovejoy was announced on Sept. 9 after two nights of photographic observations by Lovejoy with an 8-inch (20 cm) Schmidt-Cassegrain reflector. When nabbed, the comet was a faint midge of about 14.5 magnitude crossing the border between Orion and Monoceros. Subsequent observations by other amateur astronomers peg it a bit brighter at 14.0 with a small, condensed coma.


Cbet nr. 3649, issued on 2013, September 09, announces the discovery of a new comet (discovery magnitude ~14.4) by Terry Lovejoy on CCD images obtained with a 20-cm f/2.1 Schmidt-Cassegrain reflector on two nights. The new comet has been designated C/2013 R1 (LOVEJOY).
We performed follow-up measurements of this object, while it was still on the neocp. Stacking of 10 unfiltered exposures, 60-sec each, obtained remotely from MPC code Q62 (iTelescope Observatory, Siding Spring) on 2013, September 08.7, through a 0.32-m f/9.0 Ritchey-Chretien + CCD, shows that this object is a comet: sharp central condensation surrounded by a coma about 25" in diameter and a tail about 40" in PA 245.
