NGC2770

NGC2770 is a Mag 12 spiral galaxy that is estimated to be 81 million light years away (there is little other information available on the internet). 2007uy was detected on 31/12/2007. In Jan 08 an XRF was detected at a different location in the same galaxywhich built in intensity for 50s then decayed over the next 10 minutes. There was nothing visible until the next day when sn2008D was first seen. Click here for larger image.

Around 371 million years ago, in a fairly anonymous galaxy that we call MGC +5-43-16, an unusual event occurred -a star exploded in a Type II
supernova. The really unusual thing, is that this was followed two weeks later by another supernova - this time a type 1a.

  • sn2007ck is about Mag 17.5
  • sn2007co is about Mag 15.8

Exposure: 5 x 480 seconds
