Fermi trigger No 588398821 Global MASTER-Net observations report
Abstract
MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB190825.17 (trigger No 588398821, 14h 3m 26.40s , -74d 8m 24.00s, R=19.89) errorbox 51073 sec after trigger time at 2019-08-25 18:18:09 UT, with upper limit up to 19.9 mag. The observations began at zenit distance = 54 deg. The sun altitude is -26.2 deg. The galactic latitude b = -60 deg., longitude l = 98 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1115181 We obtain a following upper limits.
