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) started inspect of the Fermi GRB230225.62 (trigger No 699029364,03h 04m 02.40s , -31d 10m 48.0s, R=5.24) errorbox 11469 sec after notice time and 11502 sec after trigger time at 2023-02-25 18:01:02 UT, with upper limit up to 19.0 mag. Observations started at twilight. The observations began at zenith distance = 35 deg. The sun altitude is -9.5 deg.
The galactic latitude b = -60 deg., longitude l = 229 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2201226
We obtain a following upper limits.
