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) started inspect of the Fermi GRB220915.40 (trigger No 684927323,15h 08m 00.00s , +84d 07m 48.0s, R=6.48) errorbox 1149 sec after notice time and 15814 sec after trigger time at 2022-09-15 13:58:53 UT, with upper limit up to 17.0 mag. The observations began at zenith distance = 38 deg. The sun altitude is -33.8 deg.
The galactic latitude b = 32 deg., longitude l = 119 deg.
Real time updated cover map and OT discovered available here:
