- Аннотация: MASTER OT J155021.51+484836.6 discovery - new Dwraf Nova (Ampl>3.5), no known source in VIZIER MASTER-Tunka auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered OT source at (RA, Dec) = 15h 50m 21.51s +48d 48m 36.6s on 2015-04-19.73562 UT. The OT unfiltered magnitude is 18.5m (the limit is 19.8m). There are 3 images with OT. There is no minor planet at this place. We have reference image without OT on 2011-04-12.81332 UT with unfiltered m_lim=22.0, on 2014-04-29.678 (m_lim=20.0), on 2014-04-29.631 (m_lim=19.4, MASTER-Tunka database), and on 2011-03-15.011 (m_lim=20.5, MASTER-Kislovodsk database). There is no known sources in 5" in VIZIER database, no CRTS. The discovery and reference images are http://master.sai.msu.ru/static/OT/MASTER155021.51+484836.6.jpg MASTER OT J003026.72+475624.0 discovery - new Dwarf Nova (Ampl>5m), no source in VIZIER MASTER-Tunka auto-detection system discovered OT source at (RA, Dec) = 00h 30m 26.72s +47d 56m 24.0s on 2015-04-22.806 UT. The OT unfiltered magnitude is 17.1m (limit 18.9m). There are 4 images with OT. We have reference images without OT on 2011-12-01.518UT with 20.7 unfiltered magnitude limit, on 2012-10-20.731UT with m_lim=20.5 and on 2014-10-16.744 with m_lim=19.7m in MASTER-Tunka database and on 2010-11-03.640UT with m_lim=20.5m in MASTEr-Kislovodsk database. There are 2 stars in GSC2.3.2 in 4.5" and in 4.9", but MASTER OT is between them. There is marginally source at POSS II image, but it's not presented in any catalogue. The discovery and reference images are http://master.sai.msu.ru/static/OT/MASTER003026.72+475624.0.jpg MASTER OT J224751.44+364320.8 discovery - Dwarf Nova flare (Ampl>3.3) MASTER-Tunka auto-detection system discovered OT source at (RA, Dec) = 22h 47m 51.44s +36d 43m 20.8s on 2015-04-15.869 UT. The OT unfiltered magnitude is 16.6m (the limit is 18.1m). There are 3 images with OT. We have reference image without OT on 2013-10-11.533 with m_lim=19.5, on 2011-09-28.76272UT (m_lim=19.8), on 2013-08-02.891UT (m_lim=19.5),2012-09-16.880UT (m_lim=19.9) in MASTER-Tunka and MASTER-Kislovodsk database. There are the flares in CRTS survey => MASTER OT is Dwarf Nova flare.

The OT unfiltered mag. is 14.9. There are 4 images between 2015-04-18 13:19:06.857 and 13:35:14.274UT with m_OT=14.9. There is a USNO-A2.0 star in 2.565" with B=19.1,R=18.0 =>UVCet type flare. MASTER images are available at http://master.sai.msu.ru/static/OT/MASTER103930.78-050340.1.jpg
