K. J. Lawrence reported the discovery of a comet of magnitude 18.4 by the NEAT
team from CCD images taken with the 1.2-m Schmidt telescope at Palomar on 7
December 2002. The comet was independently recovered between 9 and 11 August
2010 by H. Taylor (Rayle, GA, U.S.A., 25-cm reflector), by H. Sato (Tokyo, Japan;
remotely, 25-cm reflector, RAS Observatory, Mayhill, NM, U.S.A.; 20" coma and 30"
tail in p.a. 260 deg), by L. Elenin (Lyubertsy, Russia; remotely, 45-cm f/2.8
astrograph, ISON-NM Observatory, Mayhill; 50" tail), and by T. Yusa (telescope data
same as for Sato; faint 25" tail in p.a. 252 deg).
