TITLE: GCN CIRCULAR NUMBER: 43898 SUBJECT: The EP-WXT trigger 01709258736: Las Cumbres discovery of the optical counterpart DATE: 26/03/03 02:34:27 GMT FROM: Wenxiong Li at NAOC <liwenxiong1992@gmail.com> Wenxiong Li (NAOC), Iair Arcavi (TAU), Ido Keinan (TAU), Runduo Liang (NAOC), David Sand (U of Arizona) We observed the position of the EP/WXT trigger 01709258736 with a Las Cumbres 1m telescope at Cerro Tololo Interamerican Observatory, Chile, 1 hour after the Einstein Probe WXT trigger. We took 2x300s exposures in each visit in the broad optical w band. We find an uncataloged source at RA=132.9739, Dec=-65.9837 within the EP/WXT error circle and measure the following preliminary photometry calibrated to the R band: MJD 61102.042 Mag 19.8 View this GCN Circular online at https://gcn.nasa.gov/circulars/43898. --- To unsubscribe, open this link in a web browser: https://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6InZzbmV0LW...
