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 GRB210303.42 (trigger No 636459103,02h 58m 07.20s , -03d 46m 48.0s, R=5.24) errorbox  23338 sec after notice time and 23365 sec after trigger time at 2021-03-03 16:41:04 UT, with upper limit up to  14.9 mag. The observations began at zenith distance = 65 deg. The sun  altitude  is -18.8 deg. 

The galactic latitude b = -51 deg., longitude l = 181 deg.
