As announced on CBET 3251, an apparently asteroidal object discovered on images taken on 2012 Sept. 17 by R. A. Kowalski in the course of the Mount Lemmon Survey (discovery observations tabulated below), and designated 2012 SB6 by the Minor Planet Center, was found to show cometary appearance by observers elsewhere. Henry Hsieh noted that images taken with the Pan-STARRS1 telescope on Oct. 8.42-8.49 UT showed a point-spread function that is extended relative to the PSF of nearby field stars. David J. Tholen and Marco Micheli noted that three 120-s follow-up images taken on Oct. 9.5 UT by Micheli and Garrett T. Elliott with the 2.24-m University of Hawaii reflector at Mauna Kea show a tail about 7" long in p.a. about 225 deg.
