TITLE: GCN CIRCULAR NUMBER: 44495 SUBJECT: EP260507a: further Liverpool Telescope observations DATE: 26/05/08 01:20:37 GMT FROM: Rob Eyles-Ferris at U of Leicester <raje1@leicester.ac.uk> R. A. J. Eyles-Ferris (Leicester) reports on behalf of a larger collaboration: We observed the field of EP260227a (Fu et al., GCN 44488) with the 2m Liverpool Telescope on La Palma using the IO:O instrument. We obtained 6x200s exposures in each of the SDSS r’ and z’ filters starting at 2026-05-07 22:51:45 UT, approximately 9.06 hours after the X-ray detection. We detect the optical counterpart (Corcoran et al., GCN 44489; Sankar et al., GCN 44490; Jiang et al., GCN 44491; Kumar et al., GCN 44492; Bochenek et al., GCN 44494) in both the r’ z’ bands and measure the following magnitudes: r’ = 22.76 +/- 0.21 z’ = 21.98 +/- 0.30 Our photometry is calibrated to Pan-STARRS and not corrected for Galactic extinction.
