Vladimir Lipunov, David Buckley and Pavel Balanutsa reports the MASTER-SAAO(twin 0.40-m f/2.5reflector + 4Kx4K CCD) auto-detection system's dicovery of the possible supernova source at (RA, Dec) = 08h 42m 32.51s -84d 30m 25.5s on 2015-11-22.03715 UT. This PSN (MASTER OT J084232.51-843025.5) is in 9.6"W and 3.3"S from the ESO006-004 galaxy. The OT unfiltered magnitude (W=0.2B+0.8R calibrated to USNO-B1) is 17.1m , the limit is 19.2m. E.Gorbovskoy and N.Tiurina report that nothing was visible at this position on the MASTER-SAAO images obtained on 2015-03-09.99288 UT with unfiltered magnitude limit 19.2m and on 2015-01-30.961UT with m_lim=19.2.
