- Аннотация: MASTER OT J205110.36+044842.2 discovery - QSO or dwarf nova, ampl>5.5m MASTER-OAFA auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 20h 51m 10.36s +04d 48m 42.2s on 2017-09-28.15049 UT. The OT unfiltered magnitude is 15.0m (mlim=18.7m). The OT is seen in 8 images. There is no minor planet at this place. There is SDSS possibly QSO in 0.137" and GALEX source in 1" We have reference image without OT on 2017-09-17.22237 UT with unfiltered magnitude limit 19.2m in MASTER-OAFA, on 2016-08-26 20:21:56Ut with mlim=20.5 in MASTER-SAAO. It means, the amplitude of current outburt is more then 5.5 Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/205110.36044842.2.png
