We observed the afterglow of GRB 120819A (Beardmore et al. GCN 13681) with
0.7m telescope of Institute of Astronomy, Kharkiv National Univ. starting
on Aug. 19 (UT) 18:27:41. A set of images were taken in R-filter. We do
not detect optical afterglow (Malesani et al. GCN 13683; Sudilovsky et
al.GCN 13688). The photometry is based on the nearby USNO-B1.0 (R2) stars:
T0+, Filter Exposure, OT, UL (3 sigma)
