Аннотация:Spectral observations are required for every OT. MASTER-SAAO auto- detection system ( Lipunov et al., “MASTER Global Robotic Net”, Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 07h 53m 05.60s -62d 01m 03.2s on 2020-02-26.97531 UT. The OT unfiltered magnitude (0.2B+0.8R by USNO-B1) is 18.5m (mlim=20.2).
