Object name: M061Designation(s): M061, NGC4292, NGC4292A, NGC4303, M61 is another galaxy in the Virgo Cluster. Distance estimates vary from a bit under 50 million to a bit over 60 million light-years. It is one of the more southern members of the group so actually is in Virgo, many are in Coma Berenices. NED classifies it as SAB(rs)bc;HII Sy2 though some sources don't agree with the Seyfert 2 classification saying it is a weak AGN instead. This galaxy has been a hotbed of supernovas with 7 seen since 1926 and 6 of those since 1961. Japanese astronomer Koichi Itagaki discovered the last two in 2008 and 2014. This image was taken on January 5, 2009. Itagaki discovered SN 2008in on December 26 so it was still bright when I took this image. It reached magnitude 14.3. When I took it I measured it at 14.9 in my red filter and 14.5 in the blue filter. Unfortunately, the night was poor so details in the galaxy are lost to poor seeing and poor transparency. This galaxy has had at least 7 supernova since 1926; SN 1926A, SN 1961I, SN 1964F, SN 1999gn, SN 2006ov, SN 2008in and SN 2014dt. It would seem this is a galaxy for SN hunters to check often.
