The OT magnitude in unfiltered is 17.9m (limit 18.7m). The OT is seen in 3 images. There is no minor planet at this place. We have reference image without OT on 2016-03-19.21341 UT with unfiltered magnitude limit 19.9m. There is no any known sources inside 5" in VIZIER database, it means the 22nd POSS limit and the amplitude of current outburt is more then 4.1m Spectral observations are required. The discovery and reference images are available at http://master.sai.msu.ru/static/OT/191840.69422103.3.png MASTER OT J033705.75-131224.9 detection - bright possibly QSO flare MASTER-IAC auto-detection system discovered OT source at (RA, Dec) = 03h 37m 05.75s -13d 12m 24.9s on 2016-07-25.22957 UT. The OT unfiltered magnitude is 15.6m (limit 17.0m). The OT is seen in 3 images. There is no minor planet at this place. We have reference image without OT on 2015-08-26.19017 UT with unfiltered magnitude limit 20.7m. This is GALEX source in 0.179" and Candidate to QSO/AGN Objects from SDSS-DR10. Spectral observations are required. The discovery and reference images are available at http://master.sai.msu.ru/static/OT/033705.75-131224.9.png MASTER OT J185300.79+452707.7 detection - outburst with Ampl>4m MASTER-IAC auto-detection system discovered OT source at (RA, Dec) = 18h 53m 00.79s +45d 27m 07.7s on 2016-07-24.03858 UT. The OT unfiltered magnitude is 15.7m (limit 18.8m). The OT is seen in 3 images. There is no minor planet at this place. We have reference image with marginally seen OT on 2015-09-16.88851 UT with 19.6 unfiltered magnitude limit (m_OT<19.6). This is KISJ185300.77+452708.4 variable star with unspecified type of variability in AAVSO database. Also there is GALEX source(that means the accretion to white dwarf and dwarf nova clasification (UG) with curent amplitude more or about 4m from MASTER database. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/185300.79452707.7.png Current outbursts: MASTER OT J204723.04+072759.1 (S.Shurpakov et al., ATEL #5255 ) was detected by our auto-detection system on 2016-07-27 01:04:52.009UT with unfiltered m_OT=15.4 (current outburst)
