GCN Circular 37869

A. Bochenek and D. A. Perley (LJMU) report:
 
We observed the field of the fast X-ray transient EP241021a (Hu et al., GCN 37834
Not found
 
 
) using the IO:O optical camera on the 2m robotic Liverpool Telescope. We obtained 6x150s exposures in the SDSS r’ filter starting at 2024-10-24 23:07:43 UT, approximately 3.25 days after the trigger.
 
We report a faint detection in the stacked images of r = 22.43 ± 0.14 mag, at a position consistent with the optical counterpart reported by Fu et al. (GCN 37840

) and other optical observations (Fu et al., GCN 37842

). The photometry was obtained using nearby PanSTARRS standards and was not corrected for extinction. The source faded approximately 0.5 mag in the last 24 hours.
