MASTER-Kislovodsk robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the MAXI GRB220514.98 (trigger No 713758386,16h 23m 00.24s , +61d 39m 18.0s, R=1) errorbox 3 sec after notice time and 2351 sec after trigger time at 2022-05-15 00:03:38 UT, with upper limit up to 14.1 mag. Observations started at twilight. The observations began at zenith distance = 26 deg. The sun altitude is -16.1 deg.
The galactic latitude b = 41 deg., longitude l = 93 deg.
Real time updated cover map and OT discovered available here:
