It is # elongated in north-south direction, and SN is located at the edge of # bright bulge region. The expected maximum for typical SN Ia is mag # about 16.7.

The # SN is superimposed on the outermost northern arm. There is a # foreground star (or a bright knot) 30" WNW of the nucleus of NGC # 2742.
