MASTER-Tavrida robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, SAI Crimea astronomical station) was pointed to the Swift GRB 200829A ( M. H. Siegel et al., GCN 28307) errorbox 12423 sec after notice time and 12502 sec after trigger time at 2020-08-29 17:27:56 UT, with upper limit up to 18.5 mag. Observations started at twilight. The observations began at zenith distance = 30 deg. The sun altitude is -11.7 deg.
The galactic latitude b = 35 deg., longitude l = 104 deg.
Real time updated cover map and OT discovered available here:
