Here is another SN image from last night. It is SN2013ag.
The location of SN2013ag is R.A. = 12h51m35s.02, Decl. = +26°37'45".4
Cartes du Ciel locates the gaylaxy PGC1783094 at J2000 RA: 12h51m35.39s DE:+26°37'44.0"
That are pretty much the same coordinates. So I think that PGC1783094 is the name of the SN's host galaxy.
The weather conditions were poor: High thin clouds and a nearly full moon.
