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) started inspect of the Fermi GRB210518.03 (trigger No 642991619,00h 18m 45.60s , -01d 36m 00.0s, R=7.86) errorbox 7334 sec after trigger time at 2021-05-18 02:49:09 UT, with upper limit up to  19.4 mag. The observations began at zenith distance = 64 deg. The sun  altitude  is -32.3 deg. 

MASTER-OAFA robotic telescope  located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB210518.03 errorbox 28099 sec after trigger time at 2021-05-18 08:35:14 UT, with upper limit up to  18.5 mag. The observations began at zenith distance = 65 deg. The sun  altitude  is -34.3 deg. 

The galactic latitude b = -63 deg., longitude l = 106 deg.
