MASTER-Tunka robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Applied Physics Institute, Irkutsk State University) was pointed to the Swift GRB230816.67 (trigger No 1185673,21h 53m 29.98s , +37d 49m 42.6s, R=0.05) errorbox 2108 sec after notice time and 2130 sec after trigger time at 2023-08-16 16:44:18 UT, with upper limit up to 17.2 mag. The observations began at zenith distance = 15 deg. The sun altitude is -25.0 deg.
The galactic latitude b = -13 deg., longitude l = 89 deg.
Real time updated cover map and OT discovered available here:
