EP241223a

We observed the field of the X-ray transient, EP241223a by the Xinglong 2.16-m telescope located at Xinglong, Hebei, China. Following the detection of EP241223a by EP-WXT (Li et al., GCN 36405), we observed the field of EP241223a using the 2.16-m telescope at Xinglong Observatory, NAOC. We obtained 6x600s clear-band frames with a median time of 2024-12-24T14:16:34, 10 hr after the EP trigger. No uncatalogued optical transient is detected in the stacked images within the 3 arcmin EP/WXT error circle (Li et al., GCN 36405), down to 5-sigma limiting magnitudes of g ~ 22.5, calibrated with Pan-STARRS sources in the field. Also there is no apparent brightening for the catalogued sources within the error circle.
