MASTER-Tavrida robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB190601.32 (trigger No 581068049, 10h 51m 55.20s , +54d 35m 24.00s, R=8.28) errorbox  40809 sec after trigger time at 2019-06-01 19:07:33 UT, with upper limit up to  19.2 mag. Observations started at twilight.  The observations began at zenit distance = 32 deg. The sun  altitude  is -15.2 deg. 

MASTER-Kislovodsk robotic telescope  located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB190601.32 errorbox  41388 sec after trigger time at 2019-06-01 19:17:12 UT, with upper limit up to  19.0 mag. The observations began at zenit distance = 39 deg. The sun  altitude  is -20.1 deg. 

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