MASTER-Kislovodsk robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB210910.38 (trigger No 652957973,19h 58m 12.00s , +35d 33m 00.0s, R=8.86) errorbox 34681 sec after notice time and 34729 sec after trigger time at 2021-09-10 18:51:38 UT, with upper limit up to 19.2 mag. The observations began at zenith distance = 12 deg. The sun altitude is -33.2 deg.
The galactic latitude b = 3 deg., longitude l = 72 deg.
Real time updated cover map and OT discovered available here:
