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) was pointed to the Swift GRB 201029A ( S. Dichiara et al., GCN 28803) errorbox 103 sec after trigger time at 2020-10-29 20:23:35 UT, with upper limit up to  17.3 mag. The observations began at zenith distance = 77 deg. The sun  altitude  is -27.6 deg. 

The galactic latitude b = 56 deg., longitude l = 73 deg.
