C/2012 L2 (LINEAR)

CBET  3135: An apparently asteroidal object discovery by the LINEAR survey (discoveryobservations tabulated below), and posted on the Minor Planet Center's NEOCP webpage, has been found to show cometary appearance by other CCD astrometrists….

I also did the observation with remote telescope: … Images obtained remotely by E. Bryssinck (Kruibeke, Belgium; 0.43-m f/6.8 astrograph + Bessel R filter at the RAS Observatory, iTelescope network, near Mayhill, NM, U.S.A.; June 5.4) show a 9" coma.
