Fermi trigger No 701883729: 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 GRB230330.65 (trigger No 701883729,23h 36m 48.00s , -71d 23m 24.0s, R=7.86) errorbox 6587 sec after notice time and 6594 sec after trigger time at 2023-03-30 17:31:58 UT, with upper limit up to 18.1 mag. Observations started at twilight. The observations began at zenith distance = 70 deg. The sun altitude is -12.3 deg. The galactic latitude b = -45 deg., longitude l = 311 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2207407 We obtain a following upper limits.
