MASTER OT J105145.85+552312.4 discovery - PSN in PGC032587 (AGN)

MASTER-IAC auto-detection system Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 349171 discovered OT source at (RA, Dec) = 10h 51m 45.85s +55d 23m 12.4s on 2016-05-31.97997 UT.
The OT unfiltered magnitude is 18.3m (limit 20.1m).
PSN is seen in 6 images.
We have reference image without OT on 2016-04-11 02:02:25UT with m_lim=20.2, on2015-11-20.19394 UT with unfiltered magnitude limit 20.4m.
This PSN is in 12.9"W and 3.7"N from PGC032587(z=0.073944) with AGN(Radio source) Spectral observations are required.

MASTER OT J190516.08+472334.1 discovery - possible dwarf nova outburst, Ampl>4.8m, no optical sources in VIZIER

MASTER-IAC auto-detection system discovered OT source at (RA, Dec) = 19h 05m 16.08s +47d 23m 34.1s on 2016-05-30.18591 UT.
The OT unfiltered magnitude is 17.2m (limit 19.2m).
The OT is seen in 3 images. There is no minor planet at this place.
We have reference image without OT on 2016-03-20.20979 UT with unfiltered magnitude limit 19.1m.
There is no known optical sources in VIZIER database it means the 22m POSS limit and Amplitude of outburst more then 4.8m
Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/190516.08472334.1.png

MASTER OT J162941.70-313616.0 discovery - bright dwarf nova outburst, Ampl>5m, no sources in VIZIER

MASTER-SAAO auto-detection system discovered OT source at (RA, Dec) = 16h 29m 41.70s -31d 36m 16.0s on 2016-05-29 23:42:41.181UT. The OT unfiltered magnitude is 17.0m (limit 19.6m). The OT is seen in 17 images on 29,30,31 of May.
We have reference image without OT on 2016-04-04.98975 UT with unfiltered magnitude limit 20.2m.
There is no any known sources in VIZIER database, it means the Amplitude of current outburst >5m Spectral observations are required.
