An apparently asteroidal object discovered by the LINEAR survey has been found to show cometary appearance by other CCD astrometrists.
L. Elenin (Lyubertsy, Russia) writes that three stacked sets of images (each composed of thirty 60-s exposures) obtained remotely with a 0.45-m f/2.8 telescope at the ISON-NM Observatory near Mayhill, NM, USA, on June 11.32 UT shows a round, diffuse coma (FWHM about 11") and a broad, short tail about 25" long in p.a. 180 deg.
