C/2012 S1, also known as Comet ISON, is a sungrazing comet discovered on 21 September 2012 by Vitali Nevski and Artyom Novichonok. The discovery was made using the 0.4-meter (16 in) reflector of the International Scientific Optical Network near Kislovodsk, Russia and the automated asteroid-discovery program CoLiTec. Precovery images by the Mount Lemmon Survey from 28 December 2011 and by Pan-STARRS from 28 January 2012 were quickly located. Follow-up observations were made on 22 September by a team from Remanzacco Observatory in Italy using the iTelescope network.The discovery was announced by the Minor Planet Center on 24 September. Observations by SWIFT suggest that C/2012 S1′s nucleus is around 5 kilometers (3.1 mi) in diameter.
