TITLE: GCN CIRCULAR NUMBER: 41605 SUBJECT: EP-WXT trigger 01709200994: Liverpool Telescope upper limits DATE: 25/08/30 10:11:26 GMT FROM: Rob Eyles-Ferris at U of Leicester <raje1@leicester.ac.uk> R. A. J. Eyles-Ferris and N. Habeeb (U of Leicester) report on behalf of a larger collaboration: We observed the field of the EP-WXT trigger 01709200994 with the 2m Liverpool Telescope using the IO:O instrument. We obtained 6x150s exposures in each of the SDSS r’ and SDSS g’ filters starting at 2025-08-29 23:55:21 UT, approximately 3.0 hours after the X-ray detection. We performed image subtraction on the stacked images using reference images from Pan-STARRS and also compared the stacked and reference images manually. We detect no new sources in either the subtractions or stacked images. This is consistent with 01709200994 being a stellar flare (Ni et al., GCN 41599; Perez-Garcia et al., GCN 41603). We derive 3-sigma upper limits of r’ > 22.6 and g’ > 22.4 with photometry calibrated to Pan-STARRS and not corrected for Galactic extinction.
