Fermi GRB 230628C: Global MASTER-Net observations report
Abstract
MASTER-OAGH robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Mexico (OAGH National Institute for Astrophysics, Optics and Electronics) started inspect of the Fermi GRB 230628C ( Fermi GBM team, GCN 34106) errorbox 61791 sec after notice time and 61823 sec after trigger time at 2023-06-29 10:46:57 UT, with upper limit up to 17.1 mag. Observations started at twilight. The observations began at zenith distance = 27 deg. The sun altitude is -16.8 deg. The galactic latitude b = 2 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=2229961 We obtain a following upper limits.
