Gabovich (Blagoveschensk Educational State University) 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 GRB240802.33 (trigger No 744278264,09h 32m 16.08s , +20d 54m 00.0s, R=34.68) errorbox 1 days 32419 sec after notice time and 1 days 32456 sec after trigger time at 2024-08-03 16:58:36 UT, with upper limit up to 16.0 mag. Observations started at twilight. The observations began at zenith distance = 71 deg. The sun altitude is -11.9 deg. The galactic latitude b = 45 deg., longitude l = 210 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2548809 We obtain a following upper limits.
