Swift GRB 210323A: Global MASTER-Net observations report
Abstract
MASTER-IAC robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Spain (IAC Teide Observatory) was pointed to the Swift GRB 210323A ( J.D. Gropp et al., GCN 29699) errorbox 20222 sec after notice time and 20288 sec after trigger time at 2021-03-24 03:40:27 UT, with upper limit up to 16.5 mag. The observations began at zenith distance = 84 deg. The sun altitude is -43.3 deg. The galactic latitude b = -16 deg., longitude l = 73 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1575256 We obtain a following upper limits.
