GCN Circular 32945
R. Strausbaugh (University of Minnesota), A. Cucchiara (NASA) report on behalf of a larger collaboration: We observed the GRB 221115B (DeLaunay et al., GCN 32941) field with the LCOGT 1-meter Sinistro instrument at the South African Astronomical Observatory site, on November 16, from 19:40 to 20:08 (corresponding to 34.15 to 34.62 hours from the GRB trigger time) with the SDSS r and i filters. We performed a series of 3x300s exposures in each band. We do not detect any fading uncatalogued sources in the BAT error region, in either band, consistent with other optical upper limits (de Wet et al., GCN 32943). The following upper limits are calculated using the Pan-STARRS catalog as reference: r > 22.4 i > 21.5 These magnitudes are not corrected for galactic extinction.
