Аннотация: MASTER OT J083256.92-035128.1 discovery - PSN in 4.6" of PGC152788
MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 08h 32m 56.92s -03d 51m 28.1s on 2017-02-11 22:13:06.767UT .
The OT unfiltered magnitude is 16.9m (mlim=19.8).
The OT is seen at 20 images. We have reference image on 2014-12-23.04911 UT with unfiltered mlim= 20.2m.
There is spiral PGC152788 in 4.6" of this OT .
Spectral observations are required.

MASTER OT J081447.89-583624.2 discovery - possibly dwarf nova outburst, Ampl>5.1
MASTER-SAAO auto-detection system discovered OT source at (RA, Dec) = 08h 14m 47.89s -58d 36m 24.2s on 2017-02-13.77013 UT.
The OT unfiltered magnitude is 16.9m (mlim=18.7). The OT is seen at 2 images on 2017-02-13, and on image on 2017-02-12 22:31:13UT with the same m_OT. There is no minor planet at this place.
We have reference image on 2015-12-17.98883 UT with unfiltered mlim=20.3m.
There is no optical source in USNO-B1, it means 22mag limit for usual state and more then 5.1m of current outburst amplitude.
Spectral observations are required.
