TITLE: GCN CIRCULAR NUMBER: 43879 SUBJECT: EP260227a: LCOGT Optical Observations DATE: 26/02/28 17:33:05 GMT FROM: Robert Strausbaugh at Eastern Illinois University <rstrausbaugh@eiu.edu> R. Strausbaugh (Eastern Illinois University), A. Cucchiara (NASA) report on behalf of a larger collaboration: We observed the EP260227a field (Wang et al., GCN 43869) with the LCOGT 1-meter Sinistro instrument at the Cerro Tololo Interamerican Observatory, Chile site, on February 28, from 05:39 to 06:00 UT (corresponding to 9.28 to 9.63 hours after the trigger time) with the SDSS r and i filters. We performed a series of 3x200s exposures in i-band and r-band. We marginally detect an uncatalogued sources in both bands, consistent with other optical detections (Eyles-Ferris et al., GCN 43867; Li et al., GCN 43868; Fu et al., GCN 43873; Mandarakas et al., GCN 43874; Eyles-Ferris et al., GCN 43875; Malesani et al., GCN 43876). The following magnitudes are calculated using the PanSTARRS catalog as reference: r = 20.78 +/- 0.58 i = 21.47 +/- 0.52 These magnitudes are not corrected for galactic extinction.
