Zach Golkhou (U. Wash.), and Vicki Toy (UMD) report:\n\nWe observed the field of GRB 171115A (Sbarufatti, et al., GCN 22124) with\nthe Reionization and Transients Infrared Camera (RATIR; www.ratir.org) on\nthe 1.5m Harold Johnson Telescope at the Observatorio Astron��mico Nacional\non Sierra San Pedro M��rtir from 2017/11 16.08 to 2017/11 16.15 UTC (7.14 to\n8.66 hours after the BAT trigger), obtaining a total of 1.07 hours exposure\nin the r and i bands and 0.38 hours exposure in the Z, Y, J, and H bands.\n\nFor a source within the Swift-XRT error circle (Beardmore, et al., GCN\n22125), in comparison with the USNO-B1 and 2MASS catalogs, we obtain the\nfollowing upper limits (3-sigma):\n\n r > 23.05\n i > 23.19\n Z > 21.86\n Y > 21.66\n J > 21.13\n H > 20.71\n\nThese magnitudes are in the AB system and are not corrected for Galactic\nextinction in the direction of the GRB.\n\nWe thank the staff of the Observatorio Astron��mico Nacional in San Pedro\nM��rtir.",
