MASTER OT J160656.39+154046.2 discovery - PSN
MASTER-IAC auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 16h 06m 56.39s +15d 40m 46.2s on 2017-05-29.98135 UT.
The OT unfiltered magnitude is 17.4m (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 2016-05-06.03264 UT with unfiltered magnitude limit 20.6m.
This PSN is in 22.4"E,23.1"N of 2MASS (and SDSS) E galaxy http://leda.univ-lyon1.fr/ledacat.cgi?2MASXJ16065485+1540231
Spectral observations are required.

MASTER OT J110810.48-713330.6 detection - possible CV

MASTER-OAFA auto-detection system discovered OT source at (RA, Dec) = 11h 08m 10.48s -71d 33m 30.6s on 2017-05-22.04545 UT.
The OT unfiltered magnitude is 17.2m (mlim=18.9m).
The OT is seen in 4 images. There is no minor planet at this place.
We have reference image without OT on 2017-01-03.26093 UT with 19.2m unfiltered magnitude limit.
Spectral observations are required.
