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 IceCube Alert 190712.05 (  5h  5m 50.38s , +13d  3m 36.00s, R=4.9599) errorbox  14574 sec after trigger time at 2019-07-12 05:18:11 UT, with upper limit up to  16.5 mag. Observations started at twilight.  The observations began at zenit distance = 78 deg. The sun  altitude  is -11.7 deg. 

MASTER-OAFA robotic telescope  located in Argentina (OAFA observatory of San Juan National University) started inspect of the IceCube Alert 190712.05 errorbox  29893 sec after trigger time at 2019-07-12 09:33:31 UT, with upper limit up to  18.5 mag. The observations began at zenit distance = 83 deg. The sun  altitude  is -25.0 deg. 

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