TITLE: GCN CIRCULAR NUMBER: 44926 SUBJECT: EP260610b: Liverpool Telescope optical upper limits DATE: 26/06/12 17:56:45 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 EP260610b (Wu et al., GCN 44895, Guo et al., GCN 44912) using the IO:O optical camera on the 2m robotic Liverpool Telescope. We obtained 8x200s exposures in SDSS gri filters, starting at 2026-06-11 00:29:50.385 UT, approximately 1.46 days after trigger. We do not detect any sources at the position of the counterpart in the stacked images (Levan et al., GCN 44897; Xin et al., GCN 44900; Zhu et al., GCN 44902; Burkhonov et al., GCN 44904; Moreno Mendez et al., GCN 44906, van Hoof et al., GCN 44915) down to the three-sigma limiting magnitude of g > 23.2, r > 23.5, i > 22.9. We note that forced PSF photometry on r-band exposures gives a two-sigma detection at 23.7 ± 0.5 mag, at a mid-observation time of 1.52 days post-trigger. The photometry is in the AB magnitude system, was calibrated using nearby PanSTARRS secondary standards, and was not corrected for extinction.
