Vladimir Lipunov reports that Pavel Balanutsa with MASTER-SAAO auto-detection system (double 0.40-m f/2.5reflector + 4Kx4K CCD) discovered OT source at (RA, Dec) = 22h 04m 43.74s -33d 13m 30.6s on 2015-07-12.90902 UT(180s exposition). Optical unfiltered (0.2B + 0.8R USNO_B1) magnitude of this possible SN is 18.5m (the limit is 20.1m). There are 3 images with this PSN (2015-07-12.90153UT, 2015-07-12.909UT, 2015-07-12.916UT). Evgeny Gorbovskoy and David Buckley report that nothing was visible at this position on MASTER-SAAO archieve images on 2015-05-25.9667 UT with 20.8 unfiltered magnitude limit. There is no minor planet at this place.
