MASTER-OAFA robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB230715.19 (trigger No 711088412,02h 22m 16.80s , -65d 10m 48.0s, R=2.07) errorbox 18 sec after notice time and 8689 sec after trigger time at 2023-07-15 06:58:17 UT, with upper limit up to 18.7 mag. The observations began at zenith distance = 53 deg. The sun altitude is -57.9 deg.
The galactic latitude b = -49 deg., longitude l = 288 deg.
Real time updated cover map and OT discovered available here:
