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 GRB240505.06 (trigger No 736564880,03h 20m 07.99s , -10d 52m 59.9s, R=35.6167) errorbox  9865 sec after notice time and 9899 sec after trigger time at 2024-05-05 04:06:14 UT, with upper limit up to  19.6 mag. Observations started at twilight.  The observations began at zenith distance = 63 deg. The sun  altitude  is -14.6 deg. 

The galactic latitude b = -51 deg., longitude l = 196 deg.


Real time updated cover map and OT discovered available here:
