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 GRB230306.67 (trigger No 699811746,13h 36m 55.20s , -30d 57m 00.0s, R=24.48) errorbox  17945 sec after notice time and 17977 sec after trigger time at 2023-03-06 21:08:39 UT, with upper limit up to  17.1 mag. The observations began at zenith distance = 63 deg. The sun  altitude  is -52.5 deg. 

The galactic latitude b = 31 deg., longitude l = 315 deg.


Real time updated cover map and OT discovered available here:
