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 GRB231129.80 (trigger No 722977823,00h 08m 09.60s , -81d 31m 48.0s, R=1) errorbox  55 sec after notice time and 90 sec after trigger time at 2023-11-29 19:11:48 UT, with upper limit up to  17.7 mag. The observations began at zenith distance = 51 deg. The sun  altitude  is -19.0 deg. 

The galactic latitude b = -36 deg., longitude l = 305 deg.


Real time updated cover map and OT discovered available here:
