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 GRB200203.14 (trigger No 602392636,16h 44m 48.00s , -52d 55m 01.2s, R=28.82) errorbox  29 sec after notice time and 59 sec after trigger time at 2020-02-03 03:18:11 UT, with upper limit up to  15.9 mag. Observations started at twilight.  The observations began at zenith distance = 38 deg. The sun  altitude  is -9.9 deg. 

MASTER-Tavrida robotic telescope  located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB200203.14 errorbox  2232 sec after notice time and 2261 sec after trigger time at 2020-02-03 03:54:53 UT, with upper limit up to  16.8 mag. Observations started at twilight.  The observations began at zenith distance = 76 deg. The sun  altitude  is -11.9 deg. 

The galactic latitude b = -5 deg., longitude l = 334 deg.
