MASTER-Amur robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical University) was pointed to the Swift GRB200115.49 (trigger No 949361,03h 45m 48.96s , +05d 36m 46.8s, R=0.05) errorbox 352 sec after notice time and 432 sec after trigger time at 2020-01-15 11:57:35 UT, with upper limit up to 17.0 mag. The observations began at zenith distance = 45 deg. The sun altitude is -38.0 deg.
The galactic latitude b = -36 deg., longitude l = 182 deg.
Real time updated cover map and OT discovered available here:
