MASTER-SAAO robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in South Africa (South African Astronomical Observatory) was pointed to the SWIFT GRB 250306A ( P. A. Evans et al., GCN 39606) errorbox  4918 sec after notice time and 5733 sec after trigger time at 2025-03-06 18:05:42 UT, with upper limit up to  18.3 mag. Observations started at twilight.  The observations began at zenith distance = 74 deg. The sun  altitude  is -12.9 deg. 

The galactic latitude b = -65 deg., longitude l = 332 deg.


Real time updated cover map and OT discovered available here:
