MASTER-IAC robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Spain (IAC Teide Observatory) started inspect of the Fermi GRB201029.85 (trigger No 625695596,14h 48m 48.00s , +51d 37m 58.8s, R=22.18) errorbox 109 sec after trigger time at 2020-10-29 20:21:41 UT, with upper limit up to  16.6 mag. The observations began at zenith distance = 81 deg. The sun  altitude  is -27.2 deg. 

The galactic latitude b = 57 deg., longitude l = 88 deg.
