This is another LOSS discovery. It was originally reported in UGC 11391, but this galaxy also has the name NGC 6745, which is much more commonly used. NGC 6745 is a complex structure of at least 3 nucleus, not two as reported in IAUC 7154. This SN isn't very bright, but because of the complex structure of the galaxy it inhabits it's a great shot.
