- Аннотация: MASTER OT J195210.21-614104.9 detection - bright (15.9) dwarf nova outburst with ampl>5.6 MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 19h 52m 10.21s -61d 41m 04.9s on 2018-03-05.05144 UT. The OT unfiltered magnitude is 15.9m(mlim=19.1). The OT is seen in 8 images. There is no minor planet at this place. We have reference images on 2015-05-20.95497 UT with unfiltered mlim= 20.5m (MASTER-SAAO), on 2017-11-24 01:03:29UT with mlim=18.5 (MASTER-OAFA). There is only B2=19.6 in USNO-B1, it means more then 5.6mag(B2,R2)-6mag(R1,B1) current amplitude and preliminary UGSU classification. Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/195210.21-614104.9.png
