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 GRB230228.69 (trigger No 699294715,17h 57m 43.92s , -15d 45m 00.0s, R=3.42) errorbox 28985 sec after notice time and 29017 sec after trigger time at 2023-03-01 00:35:27 UT, with upper limit up to 18.8 mag. The observations began at zenith distance = 73 deg. The sun altitude is -43.0 deg.
The galactic latitude b = 4 deg., longitude l = 13 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2201693
We obtain a following upper limits.
