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 201013A ( K. L. Page et al., GCN 28607) errorbox  51437 sec after notice time and 51478 sec after trigger time at 2020-10-13 18:04:29 UT, with upper limit up to  18.1 mag. The observations began at zenith distance = 73 deg. The sun  altitude  is -33.0 deg. 

The galactic latitude b = 25 deg., longitude l = 160 deg.


Real time updated cover map and OT discovered available here:
