TITLE: GCN CIRCULAR NUMBER: 43880 SUBJECT: EP260227a: Liverpool Telescope optical observations DATE: 26/02/28 20:05:03 GMT FROM: A. Bochenek at Liverpool John Moores University <a.m.bochenek@2023.ljmu.ac.uk> A. Bochenek, D. A. Perley (LJMU) report: We observed the field of EP260227a (Wang et al., GCN 43869) using the IO:O optical camera on the 2m robotic Liverpool Telescope. We obtained 5x120s exposures in SDSS r and i filters and 3x100s + 2x120s in SDSS z, starting at 2026-02-28 02:54:00 UT, approximately 6.69 hours after trigger. We report detections in stacked images in all filters at the position first reported by Eyles-Ferris et al. (GCN 43867) and Li et al. (GCN 43868). MJD (mid) T_mid-T_0 Filter Mag. (AB) 61099.12483 6.79 h r 21.31 ± 0.19 61099.13319 6.99 h i 21.10 ± 0.12 61099.14035 7.16 h z 20.71 ± 0.11 Our results are consistent with the slower fading of the optical counterpart as reported by and Eyles-Ferris et al. (GCN 43875), comparing to the observations of Fu et al. (GCN 43873), Mandarakas et al. (GCN 43874) and Eyles-Ferris et al. (GCN 43875). The photometry was obtained using nearby PanSTARRS secondary standards and was not corrected for extinction.
