Puckett Observatory Supernova Search
A spectrum of PSN J10250739+1709146 (SN 2012A) obtained on Jan. 10 by T. Pursimo with the Nordic Optical Telescope, shows it to be a type-II supernova soon after explosion.
This is another fairly bright supernova caught early in its eruption, so we are off to a flying start for 2012. My own observation on January 11th of 13.748V, taken with one of the AAVSOnet telescopes, shows the supernova has brightened considerably since discovery.
NGC 3239, also known as ARP 263, is a highly disturbed and irregular galaxy. It is located in the constellation Leo, at a distance of about 49 million light-years. The galaxy shows the effects of interaction with another galaxy.
