GCN Circular 32926
R. Strausbaugh (University of Minnesota), A. Cucchiara (NASA) report on behalf of a larger collaboration: We observed the GRB 221110A (Williams et al., GCN 32925) field with the LCOGT 1-meter Sinistro instrument at the Cerro Tololo Interamerican Observatory, Chile site, on November 10, from 03:12 to 03:40 (corresponding to 0.73 to 1.20 hours from the GRB trigger time) with the SDSS r and i filters. We performed a series of 3x300s exposures in each band. We detect an uncataloged source in the Swift error region, in both bands, consistent with the optical counterpart candidate (Lipunov et al., GCN 32924). The following magnitudes are calculated using the Pan-STARRS catalog as reference: r = 19.45 +/- 0.06 i = 18.19 +/- 0.08 These magnitudes are not corrected for galactic extinction. Imaging and spectroscopic follow-up has been conducted with Gemini and analysis is ongoing.
