- Аннотация: MASTER OT J193829.83-792552.2 discovery - new Dwarf Nova, Amplitude >5m MASTER-SAAO auto-detection system Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 discovered OT source at (RA, Dec) = 19h 38m 29.83s -79d 25m 52.2s on 2015-05-04.05270 UT. The OT unfiltered magnitude is 16.7m (the limit is 18.6m). There are 3 images with OT. There is no minor planet at this place. We have reference image without OT on 2015-04-13.00343 UT with 19.6 unfiltered magnitude limit. There is no any source in VIZIER database, so the amplitude is more than 5.3m. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/193829.83-792552.2.png Spectral observations are required. MASTER OT J205925.16-235936.6 discovery - new Dwarf Nova, Amplitude >4m MASTER-SAAO auto-detection system discovered OT source at (RA, Dec) = 20h 59m 25.16s -23d 59m 36.6s on 2015-05-01.01333 UT. The OT unfiltered magnitude is 17.8m (the limit is 18.8m). There are 3 images with OT. There is no minor planet at this place. We have reference image without OT on 2015-03-22.13247 UT with 19.3 unfiltered magnitude limit. There is no any source in VIZIER database, so the amplitude is more than 4.2m. Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/205925.16-235936.6.png
