Fermi trigger No 607537834: Global MASTER-Net observations report
Abstract
MASTER-Tunka robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB200402.69 (trigger No 607537834,12h 40m 21.60s , -06d 36m 00.0s, R=6.5) errorbox 1354 sec after notice time and 1382 sec after trigger time at 2020-04-02 16:53:32 UT, with upper limit up to 18.5 mag. The observations began at zenith distance = 61 deg. The sun altitude is -33.7 deg. The galactic latitude b = 56 deg., longitude l = 299 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1328400 We obtain a following upper limits.
