- Аннотация: 12 April 2015 is the International Day of Human Space Flight 55 years ago the greate Russian Yuriy Gagarin was the first man who started to the Space from the Earth. The USSR presents to all World this great holiday, discovered the Space for the peace human's work MASTER OT J112238.72-053950.1 discovery - QSO flare MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, v.2010, 30L) discovered OT source at (RA, Dec) = 11h 22m 38.72s -05d 39m 50.1s on 2016-04-07.88061 UT. The OT unfiltered magnitude is 16.9m (limit 20.1m). The OT is seen in 4 images. We have reference image with marginally seen OT(m_OT~20.4) on 2016-03-08 20:52:01 UT (MASTER-Kislovodsk) with 20.3 unfiltered magnitude limit. This OT is a GALEX source and a candidate to QSO Spectral observations are required. The discovery and reference images are available at http://master.sai.msu.ru/static/OT/112238.72-053950.1.png MASTER OT J084630.20-594905.4 discovery - new dwarf nova outburst, ampl>4.4m MASTER-SAAO auto-detection system discovered OT source at (RA, Dec) = 08h 46m 30.20s -59d 49m 05.4s on 2016-04-09.85997 UT. The OT unfiltered magnitude is 17.6m (limit 20.0m). The OT is seen in 6 images on 09Apr, and on 3 images on 12nd of Apr 2016. We have reference image without OT on 2015-02-22.93765 UT with unfiltered mlim=20.9m. There is no any known sources in VIZIER database, so we suggest the dwarf nova outburst with ampl>4.4m Spectral observations are required. The discovery and reference images are http://master.sai.msu.ru/static/OT/084630.20-594905.4.png MASTER OT J123325.58-333906.8 discovery - dwarf nova outburst with ampl>4m MASTER-SAAO auto-detection system discovered OT source at (RA, Dec) = 12h 33m 25.58s -33d 39m 06.8s on 2016-04-10.95120 UT with unfiltered m_OT= 17.5m (mlim=19.8m). The OT is seen in 7 images. We have reference image without OT on 2015-05-12.91859 UT with unfiltered mlim=21.3m. Spectral observations are required. There is a GSC star with blue 21.80mag in 0.961", so we suggest the dwarf nova outburst with ampl>4m. The discovery and reference images are http://master.sai.msu.ru/static/OT/123325.58-333906.8.png MASTER OT J231437.93-405351.7 discovery - optical transient, Ampl>1.6 MASTER-SAAO auto-detection system discovered OT source at (RA, Dec) = 23h 14m 37.93s -40d 53m 51.7s on 2016-04-11.11149 UT. The OT unfiltered magnitude is 18.6m (limit 20.1m). The OT is seen in 7 images. There is no minor planet at this place. We have reference image without OT on 2015-10-16.83148 UT with unfiltered magnitude limit 19.7m. There is GSC 2.3.2 source with red mag=19.71,blue mag=21.99, so the amplitude of current outburst is more then 1.5m The discovery and reference images are http://master.sai.msu.ru/static/OT/231437.93-405351.7.png MASTER OT J155546.95-174110.2 discovery - optical transient, ampl>1.6 MASTER-SAAO auto-detection system discovered OT source at (RA, Dec) = 15h 55m 46.95s -17d 41m 10.2s on 2016-04-10.93301 with unfiltered m_OT=18.6 (limit 20.6m). On the 10.90714 UT m_OT=19.9m The OT is seen in 4 images,the reference image without OT is on 2015-08-08.78911 UT with m_lim=20.2m.
