Fermi trigger No 736733320: Global MASTER-Net observations report

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 GRB240507.01 (trigger No 736733320,12h 20m 07.20s , -21d 56m 24.0s, R=8.4) errorbox 62033 sec after notice time and 62310 sec after trigger time at 2024-05-07 17:27:06 UT, with upper limit up to 19.4 mag. The observations began at zenith distance = 32 deg. The sun altitude is -19.7 deg. The galactic latitude b = 40 deg., longitude l = 294 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2446532 We obtain a following upper limits.
