Fermi trigger No 741251380: Global MASTER-Net observations report

MASTER-Tavrida robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB240628.30 (trigger No 741251380,06h 59m 12.00s , +49d 25m 01.2s, R=34.82) errorbox 44676 sec after notice time and 44697 sec after trigger time at 2024-06-28 19:34:32 UT, with upper limit up to 16.4 mag. Observations started at twilight. The observations began at zenith distance = 82 deg. The sun altitude is -16.3 deg. The galactic latitude b = 22 deg., longitude l = 168 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2510977 We obtain a following upper limits.
