Supernova 2008in in M61 (original) (raw)

[M61]

Supernova 2008in was discovered on December 26, 2008 by Koichi Itagaki when it was at about mag 14.9. This is this man's second discovery of a supernova in the galaxy M61, after SN 2006ov.

The supernova occurred at the position RA = 12:22:01.77, Dec = +04:28:47.5, or 102" E, 22" N of M61's nucleus, in the outskirts of that galaxy's eastern bright spiral arm. Two days later it was found at a maximal brightness of 14.3 mag, and from its spectrum, it was found to be of type II, i.e., hydrogen lines could be spotted; this indicates that it was a core collapse supernova of a young massive star.
