- Аннотация: MASTER OT J172543.25-732947.9 discovery - Dwarf Nova flare MASTER-SAAO auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered OT source at (RA, Dec) = 17h 25m 43.25s -73d 29m 47.9s on 2015-04-14.99043 UT. The OT unfiltered magnitude is 17.5m (the limit is 20.1m). There are 12 images with OT in MASTER-SAAO database. We have reference image without OT on 2015-03-13.007UT with m_lim=19.1, 2015-01-28.01113 UT with 19.8 unfiltered magnitude limit, on 2014-12-17.821 with m_lim=19.6 . There is 0165-0272280 USNO-B1 star with B2=18.32, R2=20.83, I=18.55. The discovery and reference images are available at:http://master.sai.msu.ru/static/OT/172543.25-732947.9.png MASTER OT J223910.79+341826.0 discovery - possible SuperNova in SDSS galaxy (GALEX UvS) MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 22h 39m 10.79s +34d 18m 26.0s on 2015-04-17.04856 UT. The OT unfiltered magnitude is 16.7m (the limit is 17.9m). There are 3 images with this PSN in MASTER-Kislovodsk database. We have reference image without OT on 2010-11-09.64832 UT with 20.2m unfiltered magnitude limit. There is SDSS J223910.15+341828.2 galaxy in 8.232" (and GALEXMSC J223910.05+341828.9 UvS). Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/223910.79341826.0.png MASTER OT J085416.79+183526.1 discovery - new Dwarf Nova MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 08h 54m 16.79s +18d 35m 26.1s on 2015-04-16.77075 UT. The OT unfiltered magnitude is 17.9m (the limit is 19.8m). There 3 images with OT in MASTER-Kislovodsk database. There is no minor planet at this place. There are 120 images without OT from 2009 up to 2015 with unfiltered m_lim from 19 to 20.1 in MASTER-Kislovodsk database (for example, on 2010-03-18.75527 UT with 20.1 unfiltered magnitude limit). There is no any known source inside 5" in VIZIER database and in CRTS history. Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/085416.79183526.1.png MASTER OT J165348.55-223445.0 discovery - Flare or variability of probable red star MASTER-SAAO auto-detection system discovered OT source at (RA, Dec) = 16h 53m 48.55s -22d 34m 45.0s on 2015-04-16.90039 UT. The OT unfiltered magnitude is 17.7m (the limit is 19.1m). There are 9 images with OT in MASTER-SAAO database (from 21:36:34.954 to 22:27:31.47 without decay). There is no minor planet at this place. We have reference images without OT on 2015-01-29.10984 UT with 19.1 unfiltered magnitude limit. There is a USNO-B1 star with R2=18.26, I=16.68 (the flare in last). No JHK. This region was observed by CRTS, but no sources during all observations at MASTER OT's RA,Dec. Not UVCet. Spectral observations are required.
