Swift GRB 210212A: Global MASTER-Net observations report
Abstract
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) was pointed to the Swift GRB 210212A ( E. Troja et al., GCN 29487) errorbox 53602 sec after notice time and 53674 sec after trigger time at 2021-02-12 19:19:52 UT, with upper limit up to 18.1 mag. The observations began at zenith distance = 44 deg. The sun altitude is -21.6 deg. The galactic latitude b = -22 deg., longitude l = 191 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1545497 We obtain a following upper limits.
