264P/Larsen = 2004 H3 = 2012 L4 Jim Larsen discovered a 19th magnitude comet in Spacewatch images of 23 April 2004. Following posting on the NEO Confirmation Page, J. E. McGaha (Tucson, AZ, 0.62-m f/5.1 reflector) reported that his stacked 3-min CCD frames taken on 24 April showed a soft coma with diameter 6" and a 8" tail in p.a. 270 deg. K Sarneczky recovered 2004 H3 on 15 June 2012 with the University of Szeged 0.60-m Schmidt at Piszekesteto Station (Konkoly), when the comet was some seven months past perihelion. The comet has a period of 7.7 years, and returned to perihelion 1.29 days earlier than predicted. Date 10x10 mag Error Kphot mag Coma ' 29-May-19 19.88 0.27 19.6 0.2
