Fermi trigger No 749735279: Global MASTER-Net observations report

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 GRB241004.49 (trigger No 749735279,18h 29m 16.08s , -09d 33m 00.0s, R=3.45) errorbox 668 sec after notice time and 689 sec after trigger time at 2024-10-04 11:59:23 UT, with upper limit up to 19.4 mag. Observations started at twilight. The observations began at zenith distance = 63 deg. The sun altitude is -13.6 deg. The galactic latitude b = -0 deg., longitude l = 22 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2625150 We obtain a following upper limits.
