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 GRB230324.05 (trigger No 701313046,09h 27m 40.80s , -48d 41m 24.0s, R=14.28) errorbox  58358 sec after notice time and 58390 sec after trigger time at 2023-03-24 17:23:51 UT, with upper limit up to  17.6 mag. Observations started at twilight.  The observations began at zenith distance = 29 deg. The sun  altitude  is -8.9 deg. 

The galactic latitude b =  2 deg., longitude l = 272 deg.
