Fermi trigger No 725857207: 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 GRB240102.13 (trigger No 725857207,12h 04m 45.60s , -16d 33m 36.0s, R=1.99) errorbox 29555 sec after notice time and 72382 sec after trigger time at 2024-01-02 23:06:24 UT, with upper limit up to 14.2 mag. The observations began at zenith distance = 71 deg. The sun altitude is -18.3 deg. The galactic latitude b = 45 deg., longitude l = 288 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2348394 We obtain a following upper limits.
