Fermi trigger No 697208885: Global MASTER-Net observations report
Abstract
MASTER-Amur robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB230204.55 (trigger No 697208885,04h 49m 57.60s , +60d 59m 24.0s, R=13.25) errorbox 692 sec after notice time and 723 sec after trigger time at 2023-02-04 13:20:04 UT, with upper limit up to 16.1 mag. The observations began at zenith distance = 9 deg. The sun altitude is -45.5 deg. The galactic latitude b = 11 deg., longitude l = 148 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2196653 We obtain a following upper limits.
