Baksan Neutrino Observatory Alert 201225.54: 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 Baksan Neutrino Observatory Alert 201225.54 (trigger No 1659617772,05h 40m 48.00s , -47d 24m 00.0s, R=3) errorbox 43582 sec after notice time and 44112 sec after trigger time at 2020-12-26 01:11:24 UT, with upper limit up to 17.7 mag. Observations started at twilight. The observations began at zenith distance = 34 deg. The sun altitude is -16.9 deg. The galactic latitude b = -31 deg., longitude l = 254 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1511597 We obtain a following upper limits.
