We observed the Chandra fast transient XRT 210423 (Lin et al., ATel #14599) with the Wafer-Scale Imager for Prime (WaSP) instrument mounted on the 200-inch Hale Telescope at Palomar Observatory. Observations started on 2021 May 6 at 07:10 UT. We acquired two sets of 6 x 300s exposures, one set in i-band and one in r-band. The data were reduced using the pipeline described in De et al. (2020), PASP, 132, 025001.
Preliminary analysis does not reveal any high-confidence transient within 1'' radius from the Chandra coordinates. Upper limits (5 sigma) are i>24.8 mag and r>25.2 mag.
