After posting on the Minor Planet Center's NEOCP webpage, many observers have commented on the cometary appearance of this 14 magnitude object, designated C/2010 G1 (BOATTINI).
The object described by the discoverer as diffuse with a strong, condensed coma about 40" in size, and a fainter coma out to a diameter about 2' that fades into the background; the coma is slightly elongated in p.a. 50-55 deg.
