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 GRB210726.80 (trigger No 1061687,12h 53m 22.08s , +19d 11m 06.0s, R=0.05) errorbox  31 sec after notice time and 54 sec after trigger time at 2021-07-26 19:19:58 UT, with upper limit up to  15.0 mag. The observations began at zenith distance = 66 deg. The sun  altitude  is -18.0 deg. 

The galactic latitude b = 82 deg., longitude l = 310 deg.
