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) was pointed to the  GRB200306.95 41 sec after notice time and 85 sec after trigger time at 2020-03-06 22:52:04 UT. On our first (20s exposure)  set we  found 1 optical transient within Swift error-box (ra=198.579 dec=11.2547 r=0.05) brighter than  17.0.
