Sergienko (Blagoveschensk Educational State University) 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) started inspect of the Fermi GRB200207.06 (trigger No 602731380,16h 16m 21.60s , -48d 18m 00.0s, R=3.24) errorbox 15375 sec after trigger time at 2020-02-07 05:39:10 UT, with upper limit up to 17.5 mag. The observations began at zenith distance = 79 deg. The sun altitude is -28.6 deg. MASTER-OAFA robotic telescope located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB200207.06 errorbox 20328 sec after trigger time at 2020-02-07 07:01:44 UT, with upper limit up to 18.2 mag. The observations began at zenith distance = 55 deg. The sun altitude is -33.6 deg. The galactic latitude b = 1 deg., longitude l = 335 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1280159 We obtain a following upper limits.
