MASTER-Tavrida robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB 210210B ( Fermi GBM team, GCN 29462) errorbox 13043 sec after notice time and 13073 sec after trigger time at 2021-02-10 20:45:00 UT, with upper limit up to 17.0 mag. The observations began at zenith distance = 67 deg. The sun altitude is -56.4 deg.
The galactic latitude b = 74 deg., longitude l = 356 deg.
Real time updated cover map and OT discovered available here:
