TITLE: GCN CIRCULAR NUMBER: 43472 SUBJECT: EP260119a: Liverpool Telescope optical follow-up observations DATE: 26/01/20 16:34:32 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 EP 260119a (Jiang et al., GCN 43447, Cheng et al. GCN 43449, Jiang et al. GCN 43465) using the IO:O optical camera on the 2m robotic Liverpool Telescope. We obtained 12x100s exposures in the SDSS r and i filters and 11x100s in SDSS z, starting at 2026-01-19 23:58:53 UT, approximately 24 hours after trigger. We report detections in the stacked images in SDSS i and z filters at the position first reported by Fortin et al. GCN 43450 and Eyles-Ferris et al. GCN 43452, as well as a non-detection in the SDSS r filter: MJD (mid) T_mid-T_0 Filter Mag. (AB) 61060.02484 24.37 h r >22.92 61060.03376 24.58 h i 22.06 ± 0.18 61060.04432 24.83 h z 20.85 ± 0.16 The photometry is consistent with measurements taken at similar time by Liu et al. GCN 43464. The photometry was obtained using nearby PanSTARRS secondary standards and was not corrected for extinction.
