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 GRB230806.17 (trigger No 712987357,04h 12m 28.80s , -07d 19m 48.0s, R=18.1) errorbox 7275 sec after notice time and 7313 sec after trigger time at 2023-08-06 06:04:26 UT, with upper limit up to 16.8 mag. The observations began at zenith distance = 72 deg. The sun altitude is -66.3 deg.
The galactic latitude b = -38 deg., longitude l = 200 deg.
Real time updated cover map and OT discovered available here:
