256P/LINEAR = 2003 HT15 = 2012 B2 An apparently asteroidal object of 18th magntiude found by LINEAR on 26 April 2003 was found to be cometary by Carl Hergenrother on images taken with the Mount Hobkins 1.2-m telescope on 24 June.  The comet had perihelion at 2.7 AU and a period of 9.9 years. An apparently asteroidal object reported by LINEAR was found to be cometary by C. Hergenrother, who reported a diffuse coma of diameter 15" (and magnitude 18.6 within an aperture of radius 8") and a broad tail 60" long in p.a. 115 deg on co-added 900-s R-band images taken on 24 June with the Mount Hopkins 1.2-m reflector. The comet was recovered at Geisei by observers T. Seki, S. Shimomoto and H. Sato on 26 January 2012 using the 0.70-m f/7 reflector + CCD.
