MASTER-Amur robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB190604.45 (trigger No 581337762, 22h 50m 12.00s , +46d 22m 12.00s, R=1) errorbox 12592 sec after trigger time at 2019-06-04 14:12:29 UT, with upper limit up to 15.5 mag. Observations started at twilight. The observations began at zenit distance = 66 deg. The sun altitude is -15.6 deg.
The galactic latitude b = -60 deg., longitude l = 98 deg.
Real time updated cover map and OT discovered available here:

We obtain a following upper limits.
Tmid-T0 | Date Time | Site | Coord (J2000) |Filt.| Expt. | Limit| Comment
