TITLE: GCN CIRCULAR NUMBER: 44809 SUBJECT: EP260602b: Liverpool Telescope and LCO observations DATE: 26/06/03 18:45:03 GMT FROM: Rob Eyles-Ferris at U of Leicester <raje1@leicester.ac.uk> R. A. J. Eyles-Ferris (Leicester), D. B. Malesani (DAWN/NBI and Radboud), J. N. D. van Dalen (Radboud), J. Chacón (PUC), F. E. Bauer (SSI and UTA), R. L. C. Starling (Leicester), P. G. Jonker (Radboud), A. J. Levan (Radboud & Warwick), report on behalf of a larger collaboration: We observed the field of EP260602b (Hu et al., GCNs 44786, 44802) with the 2m Liverpool Telescope (LT) on La Palma using the IO:O instrument and an LCO 1m telescope located at Cerro Tololo Interamerican Observatory (Chile) and equipped with the SINISTRO instrument. We obtained exposures in the Sloan r and g filters. We detect the optical counterpart (He et al., GCN 44780) in our LT and LCO r band stacked images. We obtain the following photometry for the counterpart calibrated to Pan-STARRS and not corrected for Galactic extinction: | t_mid - t_0 (hours) | Telescope/Instrument | Filter | Exposure (s) | AB magnitude | | --- | --- | --- | --- | --- | | 8.2 | LT/IO:O | r | 6x150 | 21.61 +/- 0.28 | | 8.5 | LT/IO:O | g | 6x150 | >21.80 | | 8.8 | LCO/SINISTRO | r | 5x300 | 21.68 +/- 0.23 | View this GCN Circular online at https://gcn.nasa.gov/circulars/44809. --- To unsubscribe, open this link in a web browser: https://gcn.nasa.gov/unsubscribe/eyJhbGciOiJIUzI1NiJ9.eyJlbWFpbCI6InZzbmV0LW...
