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 GRB230212.60 (trigger No 697904388,04h 06m 19.20s , +37d 51m 36.0s, R=19.41) errorbox 22498 sec after notice time and 22510 sec after trigger time at 2023-02-12 20:34:53 UT, with upper limit up to 18.3 mag. The observations began at zenith distance = 80 deg. The sun altitude is -33.6 deg.
The galactic latitude b = -10 deg., longitude l = 160 deg.
Real time updated cover map and OT discovered available here:
