A. Bochenek, D. A. Perley (LJMU) report:
We observed the field of EP260602b (Hu et al., GCN 44786) using the IO:O optical camera on the 2m robotic Liverpool Telescope. We obtained 6x150s exposures in SDSS i and z filters, starting at 2026-06-02 02:53:23 UT, approximately 8.99h hours after trigger.
We report an i-band detection at the position of the counterpart (He et al., GCN 44780; Hu et al., GCN 44802; Eyles-Ferris et al., GCN 44809), with i = 20.7 ± 0.25, and a tentative z-band detection of z = 20.8 ± 0.4 (or a 3 sigma upper limit of z > 20.4 mag).
The photometry is in the AB magnitude system, was calibrated using nearby PanSTARRS secondary standards and was not corrected for extinction.
