Eyles-Ferris (Leicester) reports on behalf of a larger collaboration:\n\nWe observed the field of the Einstein Probe WXT trigger EP01709266106 (EP260526a?) with the 2m Liverpool Telescope on La Palma using the IO:O instrument. We obtained 6x150s exposures in each of the SDSS g’r’i’z’ filters starting at 2026-05-26 21:25:48 UT, approximately 3.80 hours after the X-ray detection.\n\nWe performed image subtraction on the stacked images using reference images from Pan-STARRS and also compared the stacked and reference images manually. Within the EP/WXT localisation, we detect no new sources in any of the bands.\n\nWe derive the following 3-sigma upper limits for our stacked images. Our photometry is calibrated to PanSTARRS and not corrected for Galactic extinction.\n\n| t_mid (hours) | Filter | AB magnitude |\n| ------------- | ------ | ------------ |\n| 3.94 | r’ | >21.52 |\n| 4.24 | g’ | >21.47 |\n| 4.53 | i’ | >21.69 |\n| 4.82 | z’ | >21.25 |",
