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 MAXI GRB210110.64 (trigger No 224516204,11h 30m 38.40s , -41d 30m 36.0s, R=1) errorbox 14698 sec after notice time and 15987 sec after trigger time at 2021-01-10 19:41:11 UT, with upper limit up to 17.4 mag. The observations began at zenith distance = 80 deg. The sun altitude is -20.2 deg.
The galactic latitude b = 19 deg., longitude l = 288 deg.
Real time updated cover map and OT discovered available here:
