MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru) located in
Blagoveschensk was pointed to the GRB120819A (Beardmore et al., GCN
13681) 25 sec after notice time and 115 sec after GRB time at 2012-08-19
13:12:10.052 UT (Yurkov et. al, GCN 13682).
Unfiltered observations were carried out on high zenith distance (78 deg.
at the observations beginning moment and above).
The unfiltered magnitude is calibrated relative to USNO B1.0 (0.8 R + 0.2
B).
After the data processing we have the following results:
