MASTER-OAFA robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Argentina (OAFA observatory of San Juan National University) started inspect of the LIGO/Virgo S200114f errorbox  380 sec after trigger time at 2020-01-14 02:14:38 UT, with upper limit up to  18.2 mag. The observations began at zenith distance = 58 deg. The sun  altitude  is -26.5 deg. 

MASTER-Kislovodsk robotic telescope  located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the LIGO/Virgo S200114f errorbox  381 sec after trigger time at 2020-01-14 02:14:39 UT, with upper limit up to  17.5 mag. The observations began at zenith distance = 69 deg. The sun  altitude  is -26.1 deg. 

The galactic latitude b = -60 deg., longitude l = 98 deg.
