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 201015A ( V. D'Elia et al., GCN 28632) errorbox 88 sec after trigger time at 2020-10-15 22:51:41 UT, with upper limit up to 18.5 mag. The observations began at zenith distance = 33 deg. The sun altitude is -50.5 deg.
The galactic latitude b = -8 deg., longitude l = 112 deg.
Real time updated cover map and OT discovered available here:
