S1, also known as Comet ISON or Comet Nevski–Novichonok,
is a sungrazing comet discovered on 21 September 2012 by
Vitali Nevski (Виталий Невский, Vitebsk, Belarus) and Artyom
Novichonok (Артём Новичонок,Kondopoga, Russia). 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. |
