Supernova in M65

M65 with Supernova SN 2013am. See older picture taken some years ago for comparison. I am proud to say I discovered this by my self March 30, but only to learn that K. Sugano Japan discovered this first March 21. Official name is M65 SN2013am.

Supernova in galaxy M101

24. of August this year, Oxford university astronomers discovered a Supernova called SN2011fe, in the Pinnwheel galaxy M101 in Ursa Minor. See the circle marker in the photo taken in 17 Sept 2009. The Supernova has brightened day by day since its discovery, quite astonishing! As comparison I have added the last picture I have taken of the galaxy in April 2009.

The Fireworks Galaxy NGC6946

The NGC6946 galaxy 1o MLY away between Cepheus and Cygnus is a spiral galaxy known to have had more than 10 Supernovas the last 100 years. As comparison, we believe the rate of Supernovas in the Milkyway is about 1-2 Supernovas every 100 year. But the last one was 400 years ago!
