MASTER-Amur robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB240502.91 (trigger No 736379109,11h 07m 31.20s , +66d 18m 00.0s, R=8.19) errorbox 55169 sec after notice time and 55202 sec after trigger time at 2024-05-03 13:05:06 UT, with upper limit up to 18.5 mag. The observations began at zenith distance = 16 deg. The sun altitude is -17.1 deg.
The galactic latitude b = 48 deg., longitude l = 138 deg.
Real time updated cover map and OT discovered available here:
