- Аннотация: MASTER-Amur robotic telescope (Global MASTER-Net http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, v.2010, 30L) was pointed to Swift GRB190203B (Lien et al. GCN23845, Ttrig=2019-02-03 15:44:08 UT) 19 sec after notice time (63 sec after trigger time) at 2019-02-03 15:45:11 UT. On our first (10s exposure) set we found 1 optical transient within SWIFT error-box: T-Tmid Date Time Exp,s Ra Dec Mag ---------|---------------------|-------|-----------------|-----------------|------- 68 2019-02-03 15:45:11 10 (01h 30m 23.25s , +55d 43m 20.59s) 15.28 There is fast decay on the light curve. The 5-sigma upper limit on the first 10s exposition was 16.3mag The galactic latitude b = -6 deg., longitude l = 129 deg. The observations started on zenit distance = 61 deg. The sun altitude was -56.2 deg The message may be cited.
