Stuart Parker, Canterbury, New Zealand, reports the discovery of an apparent supernova (red mag 16.4) on a 30-s unfiltered CCD image (limiting mag 18)
taken by himself with a 30-cm Astro-Tech AT12RC Ritchey-Chretien astrograph (+ ST10 camera) at his Parkdale Observatory in the course of the Backyard Observatory Supernova Search.Which is 1E"and 20S"of the nucleus of the galaxy ESO101-G-20 (PGC59334)
