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 GRB210726.11 (trigger No 648959581,11h 34m 52.80s , -18d 19m 12.0s, R=7.27) errorbox 45460 sec after notice time and 53674 sec after trigger time at 2021-07-26 17:27:31 UT, with upper limit up to 19.1 mag. The observations began at zenith distance = 50 deg. The sun altitude is -18.8 deg.
The galactic latitude b = 41 deg., longitude l = 279 deg.
Real time updated cover map and OT discovered available here:
