MASTER OT J150803.15-270155.0 discovery- PSN in 1"E,0.8"N of 2MASXJ15080310-2701553 galaxy or AGN flare
MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net",Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 15h 08m 03.15s -27d 01m 55.0s on 2018-03-18 01:43:02.836 UT.
The OT unfiltered magnitude is 17.1m (limit 20.1m).
The OT is seen in 6 images. There is no minor planet at this place.
We have reference image without OT on 2016-05-11 19:40:33UT with 20.0 unfiltered magnitude limit.
This galaxy is in GLADE catalog (Dalya+, 2016), and is a candidate to AGN (Edelson+, 2012)
see VIZIER database
Spectral observations are required.
