C/2012 S1 ISON & C/2013 H1 La Sagra 2013.04.19

The comet C/2012 S1 ISON continues at mag 15.9R and shows a tail around 30 arc seconds long in position angle 90 degrees.

Comet ISON is potentially the "comet of the century" because it is expected to become very bright when approaching the perihelion.

ISON stands for International Scientific Optical Network, a group of observatories in ten countries organized to detect and track objects in space, it is managed by the Keldysh Institute of Applied Mathematics, part of the Russian Academy of Sciences. 

A new object found by the J75 survey La Sagra and posted on the NEOCP has shown cometary features in the initial and confirmation images by various observatories. The initial orbit a=2.5 e = 0.5 has been found to be cometary with a = 27 and e = 1.0, a  parabolic, long period orbit.
