GRB 211105A: MASTER optical inspection
Abstract
MASTER Global robotic net (MASTER-Net:http://observ.pereplet.ru Lipunov et al.,2010,Advances in Astronomy,2010,30L) started inspect of GECAM GRB 211105A (Zhao et al. GCN 31046, R.A.Dec(2000)=81.93,-57.38 +-1.27d; Ttrigger=2021-11-05T 04:35:20.200 UT, Tnotice=2021-11-06 01:59:33UT) by MASTER-OAFA (Argentina) at 2021-11-06 07:10:26UT (1 day 9306s after trigger time) with upper limit up to 19.7 mag. The observations began at zenith distance = 26 deg. The sun altitude is -27.4 deg. The galactic latitude b = -34 deg., longitude l = 266 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1777102 We obtained the following upper limits.
