We observed GRB 160815A (Markwardt et al. GCN 19794) with
GWAC-F60A 60cm optical telescope at 17:10:08 UT, Aug. 15th 2016,
about 5.41 hours after the burst.
The optical afterglow (Marshall et al., GCN 19795; LaPorte et al., GCN 19081)
was not detected in our 20*300 sec stacked R-band images down to the 3 sigma
limit of about 19.7 mag at the mid time of 6.42 hours after the burst.
The brightness was calibrated by USNO B1.0 stars.
GWAC-F60A is operated by Guangxi university and NAOC, CAS,
at Xinglong observatory, China.
