MASTER-Tavrida robotic telescope  (Global MASTER-Net:, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, SAI Crimea astronomical station) was pointed to the Swift GRB201006.05 (trigger No 998907,04h 07m 31.20s , +65d 09m 00.0s, R=0.05) errorbox 66 sec after trigger time at 2020-10-06 01:18:58 UT, with upper limit up to  18.0 mag. The observations began at zenith distance = 22 deg. The sun  altitude  is -26.9 deg. 

The galactic latitude b = 10 deg., longitude l = 142 deg.

Real time updated cover map and OT discovered available here:

We obtain a following upper limits.
