- Аннотация: MASTER OT J094505.87-654343.3 discovery - new OT, no VIZIER data, Ampl>4.5m MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 09h 45m 05.87s -65d 43m 43.3s on 2017-02-15.91771 UT. The OT unfiltered magnitude is 17.5m (mlim=18.6). The OT is seen in 4 images. We have reference image on 2015-01-06.03495 UT with unfiltered mlim= 18.9m. There is no any source in VIZIER (22mag POSS limit), it means more then 4.5mag of current outburst amplitude. Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/094505.87-654343.3.png MASTER OT J161546.98-624232.7 discovery - OT with Ampl>5m MASTER-SAAO auto-detection system discovered OT source at (RA, Dec) = 16h 15m 46.98s -62d 42m 32.7s on 2017-02-12.04274 UT. The OT unfiltered magnitude is 17.0m (mlim=18.2). The OT is seen in 3 images. There is no minor planet at this place. We have reference image on 2016-03-28.10473 UT with unfiltered mlim= 18.8m. There is GSC2.3.2 star (previous outburst in 1993.534), it means 22m POSS limit and more then 5mag amplitude of current outburst. Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/MASTEROTJ161546.98-624232.7.png MASTER OT J002049.54+280020.5 discovery - QSO flare, Ampl>5.8mag MASTER-Tunka auto-detection system discovered OT source at (RA, Dec) = 00h 20m 49.54s +28d 00m 20.5s on 2017-02-09 13:33:02.649 UT. The OT unfiltered magnitude is 14.0m (limit 18.1m). The OT is seen in 11 images. We have reference image without OT on 2011-09-03.67123 UT with unfiltered magnitude limit 19.8m, it means more then 5.8 mag of current amplitude This OT is a source from QSOs catalogue(Richards+, 2015) Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/002049.54280020.5_1.png
