- Аннотация: https://gcn.gsfc.nasa.gov/gcn3/28208.gcn3MASTER Global Robotic Net started Fermi GRB 200803B( Fermi GBM team, GCN 28201) errorbox 27 sec after notice time (55 sec after trigger time) at 2020-08-03 16:53:38 UT, with upper limit up to 18.6 mag. (GCN 28204)Observations started at twilight at zenith distance = 10 deg, the sun altitude was -10.9 deg.The cover map with discovered OT is at alert pagehttps://master.sai.msu.ru/site/master2/event.php?id=1413139MASTER OT J144603.45-413156.7 discovery (AT2020qvn)During these alert observations (Fermi inspection, open mode for twin MASTER, and fast coverage of large error-box by 8 square deg.)MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at(RA, Dec) = 14h 46m 03.45s -41d 31m 56.7s on 2020-08-03.70644 UT.The OT unfiltered magnitude is 17.9m (mlim=18.1).The OT is seen in 5 images. There is no any known sources in VIZIER and minor planet at this placeWe have reference image on 2017-05-28.87608 UT with unfiltered mlim=20.9m.Spectral observations are required (it also can be MilkyWay's CV, PSN in 52" from 6df galaxy (z=0.05128, B=16.96,R=15.97, too far for PSN but can be).The discovery and reference images are available at:http://master.sai.msu.ru/static/OT/144603.45-413156.7.pngSpectral observations and deep photometry are required.
