LAT GRB240118.08: 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) was pointed to the LAT GRB240118.08 (trigger No 727235294,01h 14m 18.00s , +29d 47m 20.4s, R=0.05) errorbox 10304 sec after notice time and 31631 sec after trigger time at 2024-01-18 10:35:21 UT, with upper limit up to 18.5 mag. Observations started at twilight. The observations began at zenith distance = 21 deg. The sun altitude is -9.7 deg. The galactic latitude b = -32 deg., longitude l = 130 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2359238 We obtain a following upper limits.
