MASTER OT J135130.87-525534.4 (2019fcc) - OT inside PGC087378
MASTER-OAFA auto-detection system ( <A
HREF="http://www.hindawi.com/journals/aa/2010/349171/">Lipunov et al.,
"MASTER Global Robotic Net",
Advances in Astronomy, 2010, 30L</A> ) discovered OT source at (RA, Dec) =
13h 51m 30.87s -52d 55m 34.4s on 2019-05-12.29047 UT.
The OT unfiltered magnitude is ~ 17m (mlim=18.4m).
The OT is seen in 2 images. There is no minor planet at this place.
We have reference image without OT on 2016-07-06.02547 UT with magnitude
limit in 'clear' filter 19.0m.
THe OT offset from center of the PGC087378 galaxy is 2.1E 11S.
The distance is about ~50Mpc.
The same transient we see 12 hours after trigger time in MASTER-SAAO
database.
Folow up observations are required.
