- Аннотация: MASTER OT J183627.60-473518.1 detection during Fermi 507696568 trigger inspection MASTER-OAFA auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 18h 36m 27.60s -47d 35m 18.1s on 2017-02-02.36706 UT. The OT unfiltered magnitude is 16.2m (mlim=18.1m). This OT was detected during Fermi trigger 507696568 inspection https://gcn.gsfc.nasa.gov/other/507696568.fermi (GRB_TIME: 2017-02-02 02:49:23.77 UT) . The OT is seen in 3 images: 2017-02-02 08:37:10.668 16.0 2017-02-02 08:48:34.421 16.0 2017-02-03 08:38:15.671 16.7 (this values means no connection with GRB counterpart, most possibly dwarf nova outburst) We have reference image without OT on 2016-08-07.07241 UT with 19.4m unfiltered magnitude limit. There is USNO-B1 star in 0.8" with R1=20.02, B2=18.65, it means current outburst amplitude more then 3m (MASTER W is calibrated by USNO as W=0.2B+0.8R) Spectral observations are required.
