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 GRB230729.29 (trigger No 712306969,00h 02m 12.00s , -62d 14m 59.6s, R=12.01) errorbox 1 days 12030 sec after notice time and 1 days 12066 sec after trigger time at 2023-07-30 10:23:50 UT, with upper limit up to 19.5 mag. Observations started at twilight. The observations began at zenith distance = 28 deg. The sun altitude is -13.0 deg.
The galactic latitude b = -54 deg., longitude l = 312 deg.
Real time updated cover map and OT discovered available here:
