Fermi trigger No 706317104: Global MASTER-Net observations report
Abstract
MASTER-OAFA robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB230520.97 (trigger No 706317104,02h 06m 57.60s , -62d 06m 00.0s, R=1) errorbox 876 sec after notice time and 891 sec after trigger time at 2023-05-20 23:26:30 UT, with upper limit up to 17.4 mag. The observations began at zenith distance = 79 deg. The sun altitude is -21.6 deg. The galactic latitude b = -53 deg., longitude l = 288 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2217848 We obtain a following upper limits.
