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) was pointed to the  GRB200306.95 20 sec after notice time and 63 sec after trigger time at 2020-03-06 22:51:42 UT. On our first (10s exposure)  set we  found 1 optical transient within Swift error-box (ra=198.579 dec=11.2547 r=0.05) brighter than  16.3.
