MASTER OT J063011.82-293839.8 discovery - new fast OT, ampl>4.4m
MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 06h 30m 11.82s -29d 38m 39.8s on 2017-11-23.00392 UT
during Fermi 532987324 trigger inspection (GRB_DATE:17/11/21 20:01:59.97UT), but not connected with this GRB .
The OT unfiltered magnitude are
2017-11-23 00:05:39.302UT 19.4 (mlim=19.6)
2017-11-23 00:08:59.888UT 17.6 (mlim=19.5).
There are only 2 inspect images of this area. There is no minor planet at this place. There is any known sources in VIZIER database, it means 22m from POSS in history and more then 4.4mag of current outburst amplitude.
We have reference image on 2017-10-23.07968 UT with unfiltered mlim= 20.2m.
Spectral observations are required.
The discovery and reference images are available at:
