- Аннотация: MASTEROT J201931.07-460044.6 discovery - Dwarf Nova flare MASTER-SAAO auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered the 800-th MASTER OT source at (RA, Dec) = 20h 19m 31.07s -46d 00m 44.6s on 2015-04-26.08954 UT. The OT unfiltered magnitude is 18.4m (the limit is 20.1m). There are 4 images with OT, full time between first and last exposition is 40min, m_OT is the same. We have reference images without OT on 2015-04-22.08853 UT with 20.8 unfiltered magnitude limit, on 2015-04-24.111 UT with m_lim=20.1 , on 2015-04-12.086 UT with m_lim=20.5. There is no minor planet at this place. There is no sources in CRTS, the area was observed. There is a GSC2.3.2 star with bmag=22.22, rmag=20.78 (previous burst of this dwarf nova). No 2MASS source. => MASTER OT is Dwarf Nova flare with Ampl>3.0m Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/201931.07-460044.6.png
