MASTER OT J015052.97-451015.9 detection - dwarf nova outburst with ampl>3m
MASTER-OAFA auto-detection system (Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 01h 50m 52.97s -45d 10m 15.9s on 2016-10-06.21896 UT with unfiltered m_OT=17.4m (limit 20.6m).
The OT is seen in 3 images. There is no minor planet at this place.
We have reference image without OT on 2016-08-03.30244 UT with unfiltered (W=0.2B+0.8R calibrated by USNO-B1) mlim=20.8m.
Spectral observations are required.
The discovery and reference images are available at http://master.sai.msu.ru/static/OT/015052.97-451015.9.png

MASTER OT J024224.27+174259.0 detection - QSO flare
MASTER-IAC auto-detection system discovered OT source at (RA, Dec) = 02h 42m 24.27s +17d 42m 59.0s on 2016-10-10.14709 UT with unfiltered m_OT=19.1m (mlim=20.2m).
The OT is seen in 7 images. We have reference image without OT on 2016-01-01.82020 UT with unfiltered magnitude limit 20.7m. There is a QSO in 0.5" in VIZIER data.
Spectral observations are required.

MASTER OT J024818.12+362104.7 detection - dwarf nova outburst, ampl>5.6m
MASTER-IAC auto-detection system discovered OT source at (RA, Dec) = 02h 48m 18.12s +36d 21m 04.7s on 2016-10-11.04424 UT with unfiltered m_OT=16.4m (mlim=19.1m).
The OT is seen in 3 images. There is no minor planet at this place.
We have reference image without OT on 2016-09-02.19590 UT with unfiltered magnitude limit 20.2m. There is a source with 22m POSS red limit, GSC2.3.2 blue jmag=21.73, GALEX source => accretion to white dwarf, dwarf nova outburst.
Spectral observations are required.
