Comet C/2012 S1 (ISON)


 2013 December

The comet did not survive perihelion at the end of November.

 2013 Apr 3

This comet is predicted to be really very bright later this year (November) but at its current distance it is rather insignificant. It is on the border between Gemini and Auriga, 4.2au from us and the same distance from the Sun (ie, nearly out at Jupiter's orbit). During the exposure of this photo it did not move against the stars, as far as I could detect.
