telescope of CrAO observatory on between Aug. 2 (UT) 22:03 and Aug. 3
(UT) 00:27 under variable weather conditions and a mean seeing of 2.1
arsces. We took several frames with exposure of 60 s in R-band. On a stacked
image we detected the optical counterpart (Pasquale et al. GCN 12228, Zheng
et al. GCN 12229). A photometry is based on the USNO B1.0 star 1709-0023450
(05 57 24.91 +80 57 39.8) assuming R=15.73.
