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 GRB 221215B ( Fermi GBM team, GCN 33058) errorbox  533 sec after notice time and 567 sec after trigger time at 2022-12-15 16:19:02 UT, with upper limit up to  19.9 mag. The observations began at zenith distance = 14 deg. The sun  altitude  is -28.7 deg. 

The galactic latitude b = -30 deg., longitude l = 134 deg.
