TITLE: GCN CIRCULAR NUMBER: 43577 SUBJECT: EP260131a: Las Cumbres detection of an optical counterpart DATE: 26/01/31 05:12:32 GMT FROM: Wenxiong Li at NAOC <liwenxiong1992@gmail.com> Wenxiong Li, Runduo Liang (NAOC), Iair Arcavi (TAU), Ido Keinan (TAU), David Sand (U of Arizona) We observed the position of EP260131a with a Las Cumbres 1m telescope at Cerro Tololo Inter-American Observatory, Chile, ~1 hour after the Einstein Probe WXT trigger. We took 2x300s exposures in the broad optical w band. We find a uncataloged source at RA=149.9025, Dec=-3.3073 within the EP-FXT error circle and measure the following preliminary photometry calibrated to the r band: MJD 61071.183 Mag 20.9 Additional followup is encouraged.
