MASTER II  robotic telescope (MASTER-Net: http://observ.pereplet.ru) 
located in Blagoveschensk was pointed to the  GRB140819.58 27 sec after 
notice time and 58 sec after trigger time at 2014-08-19 13:50:28 UT. On 
our first (10s exposure)  set we  found 1 optical transient within FERMI 
error-box (ra=16 44 07 dec=-10 58 00 r=35.270000) :

    RA                DEC
16h 45m 20.22s  -10d 06m 43.0s
m (unfiltered) = 10.4
FWHM = 2.034

The discovery image is available at

The 5-sigma upper limit has been about 12.6 mag
There is no OT on the next images!
