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 GRB210210.59 (trigger No 634659312,19h 29m 52.80s , +36d 35m 24.0s, R=7.78) errorbox 32080 sec after notice time and 32122 sec after trigger time at 2021-02-10 23:10:29 UT, with upper limit up to 16.8 mag. The observations began at zenith distance = 79 deg. The sun altitude is -56.3 deg.
The galactic latitude b = 9 deg., longitude l = 70 deg.
