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) started inspect of the Fermi GRB240805.41 (trigger No 744544656,07h 19m 40.80s , -80d 25m 12.0s, R=3.23) errorbox 49719 sec after notice time and 49751 sec after trigger time at 2024-08-05 23:46:43 UT, with upper limit up to 19.1 mag. The observations began at zenith distance = 65 deg. The sun altitude is -69.2 deg.
The galactic latitude b = -26 deg., longitude l = 292 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2551555
We obtain a following upper limits.
