Аннотация: MASTER OT J121151.82-023527.9 discovery - PSN in SDSS J121151.68-023529.8 galaxy
MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 349171 ) discovered OT source at (RA, Dec) = 12h 11m 51.82s -02d 35m 27.9s on 2016-07-07.77319 UT.
The OT unfiltered magnitude is 17.1m (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 2015-06-13.81650 UT with unfiltered magnitude limit 20.0m.
This PSN is in 2.83" from the center of Sloan galaxy with r_mag=19.3
Spectral observations are required.
