Probable Supernova 2008iz in M82

Possible Supernova 2008iz was detected in M82 on April 8, 2009 in observations made on March 24, 2008 in the radio light at 22 GHz with the Very Large Array (VLA) by Brunthaler et.al (Brunthaler et.al 2009). It had been measured again on May 3, 2008, but not found in the visible light. Initially to June 2009, it had not been sure if this object was actually a supernova or another type of transient radio object, more evidence has been made later for its supernova nature: It is now calssified as a radio supernova of type II.
