TITLE: GCN CIRCULAR NUMBER: 44658 SUBJECT: GRB 260515A: further Liverpool Telescope observations DATE: 26/05/17 08:10:40 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 GRB 260515A (Brunetet al., GCN 44622) using the IO:O optical camera on the 2m robotic Liverpool Telescope. We obtained 5x110s exposures in SDSS r and i filters, starting at 2026-05-12 00:42:25 UT, approximately 5.55 hours after trigger. We detect a source in the stacked images in both filters at the position reported by He et al. (GCN 44623), and observed also by Saccardi et al., GCN 44624; Sosnovskij et al., GCN 44625; He et al., GCN 44626; Wu et al., GCN 44628, Dennefeld et al., GCN 44633; Li et al., GCN 44634, Antier et al., GCN 44643; Dimple et al. GCN 44646; and Moskvitin et al., GCN 44652: MJD (mid) T_mid-T_0 Filter Mag. (AB) 61176.03308 5.64 h r 21.32 ± 0.06 61176.04059 5.82 h i 21.26 ± 0.07 The photometry was calibrated using nearby PanSTARRS secondary standards and was not corrected for extinction.
