- Аннотация: MASTER OT J113418.80-513313.5 discovery during Fermi GBM trigger 508270281 inspection MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 11h 34m 18.80s -51d 33m 13.5s on 2017-02-08.93060 UT. The OT unfiltered magnitude is 17.9m (mlim=18.4). This OT was discovered during Fermi GBM 508270281 trigger (GRBtime=2017/02/08 18:11:16.40 UT https://gcn.gsfc.nasa.gov/other/508270281.fermi ) The OT is seen in 4 images 2017-02-08 22:20:04.657 2017-02-08 22:21:37.16 2017-02-08 22:23:10.657 2017-02-08 22:29:43.246 We have reference image on 2015-01-11.90078 UT with unfiltered mlim= 19.1m. There is GALEX source in 1" (accretion), so we suggest the dwarf nova outburst with ampl>4.1m (no known optical sources in VIZIER, it means as minimum POSS 22m limit in history) In classic scenario this OT shouldn't be connected with GRB, spectral observations and deep photometry are required.
