telescope at Lulin Observatory, Taiwan) started at 10.9 UT. No
variable source was detected in the XRT error region (Fox et al. GCN
4629) at our co-add R and I band images. The limiting magnitude of I
and R band were calibrated against USNO-B1.0 catalog.
Mid-UT(hrs) Exp-time Filter limiting mag. (3-sigma)
