TITLE: GCN CIRCULAR NUMBER: 41695 SUBJECT: EP-WXT trigger 01709201209: Liverpool Telescope upper limits DATE: 25/09/04 13:04:23 GMT FROM: Rob Eyles-Ferris at U of Leicester <raje1@leicester.ac.uk> R. A. J. Eyles-Ferris, N. Habeeb and R. L. C. Starling (U of Leicester) report on behalf of a larger collaboration: We observed the field of the EP-WXT trigger 01709201209 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 04:15:08 UT, approximately 51 minutes after the X-ray detection. We compared the stacked images to reference images from Pan-STARRS. We also used the reference images to perform image subtraction but note that there is significant artefacting due to the bright stars in the centre of the field. We detect no new sources in either the subtractions or stacked images. This is consistent with 01709201209 being a stellar flare (Li et al., GCN 41690). We derive 3-sigma upper limits of r’ > 22.2 and g’ > 22.5 with photometry calibrated to Pan-STARRS and not corrected for Galactic extinction.
