Description:
This recently discovered type Ia supernova was visible with averted vision.  Its
parent galaxy NGC 3169 and nearby NGC 3166, both Herschel 400 spiral galaxies, were easily seen.  SN 2003cg was within the glow of NGC 3169 (see http://messier45.com/cgi-bin/h400/i.cgi?n=3169&d=GX) making a sighting somewhat
difficult.  The supernova is situated 14" east and 5" north of NGC 3169's nucleus.  An 11.3 magnitude field star lies almost due east.
