MASTER-SAAO robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in South Africa (South African Astronomical Observatory) was pointed to the SWIFT GRB210724.84 (trigger No 1061482,15h 09m 37.68s , -06d 16m 26.4s, R=0.05) errorbox  21 sec after notice time and 566 sec after trigger time at 2021-07-24 20:23:35 UT, with upper limit up to  17.2 mag. The observations began at zenith distance = 46 deg. The sun  altitude  is -56.0 deg. 

MASTER-Tavrida robotic telescope  located in Russia (Lomonosov MSU, SAI Crimea astronomical station) was pointed to the SWIFT GRB210724.84 errorbox  28 sec after notice time and 573 sec after trigger time at 2021-07-24 20:23:42 UT, with upper limit up to  15.3 mag. The observations began at zenith distance = 71 deg. The sun  altitude  is -23.3 deg. 

The galactic latitude b = 42 deg., longitude l = 354 deg.
