Comet C/2013 R1 (Lovejoy)

Object information

Comet C/2013 R1 Lovejoy has been discovered on September 9 2013. According to preliminary data it will reach its perihelion on Christmas day 2013.

This site shows the current location in the sky, and other relevant information about Comet ISON in real time. Comet's precise position is obtained from the JPL Horizons service which provides ephemerides for solar system bodies.

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.

Astronomy databases

This online sky chart is created using the following astronomy databases and services:

  1. The Digitized Sky Survey, a photographic survey of the whole sky created using images from different telescopes, including the Oschin Schmidt Telescope on Palomar Mountain
  2. The Hipparcos Star Catalogue, containing more than 100.000 bright stars
  3. The PGC 2003 Catalogue, containing information about 1 million galaxies
  4. The GSC 2.3 Catalogue, containing information about more than 2 billion stars and galaxies

About the data, and how to use it

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.
