Swift GRB240516.15: 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) was pointed to the Swift GRB240516.15 (trigger No 1228797,14h 11m 04.80s , -63d 30m 18.0s, R=0.05) errorbox 18 sec after notice time and 45 sec after trigger time at 2024-05-16 03:37:13 UT, with upper limit up to 17.3 mag. The observations began at zenith distance = 65 deg. The sun altitude is -21.9 deg. The galactic latitude b = -2 deg., longitude l = 312 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2458686 We obtain a following upper limits.
