UGC 11919 - Spiral Galaxy with Supernova PSN J22081243+4110503

UGC 11919 with supernova PSN J22081243+4110503 (Lacerta) PSN J22081243+4110503 (Type Ic, z=0.018) was discovered 2014/09/28.800 by Massimo Caimmi at magnitude ~ +19 (Rochester Supernova site | Discovery Image / RGB Image ) The image below was taken 30.0 days after discovery  The supernova is indicated by white markers. The image is unable to resolve the Supernova separately to the galaxy centre. Combined brightness of supernova and galaxy center is +12.82
