Comet ISON (C/2012 S1) was discovered by V. Nevski and A. Novichonok on September 21 2012. The name ISON comes from "International Scientific Optical Network" which is the name of the observatory used to make the discovery.
ISON reached its perihelion on November 28 2013 and according to current data (early December 2013) it's nucleus went almost completely destroyed by the intense heat caused by the close approach to the Sun's surface.
Please note. We are still showing Comet ISON on TheSkyLive.com because, even if it's nucleus has been destroyed, what remains of it will continue moving along the same predicted orbit, and hopefullly will be visible with larger telescopes. While the predicted position should be accurate, the value of the magnitude is currently not correct, since it's computation is still based on the assumption that the comet would have survived the close encounter with the Sun.
This finder chart shows an accurate view of the star field surrounding the comet, simulating a telesopic view. It is obtained from the Digitized Sky Surcvey 2, which is a photographic archive covering large part of the sky.
The chart covers an area of 45x30 arc minutes, which is roughly equivalent of full Moon's apparent size.

This online sky chart is created using the following astronomy databases and services:
TheSkyLive.com offers live information, ephemeris computations, astronomical sky charts for the most important Solar System objects. You can use the live position charts during your observation sessions, to point your telescope and identify the object on the sky background. The ephemeris computations feature can be used to plan your astronomical observations in the future.
Please note: we aim to provide high quality data obtained from the JPL Horizons ephemeris service. Please keep in mind that for objects like comets, there might be high discrepancies between the magnitude information we are showing here and the actual value. This happens because comets' magnitude is highly influenced by physical phenomena which can be hardly modelled and calculated in advance.
