We observed the field of GRB 160119A (Marshall, et al., GCN 18893) with the
Reionization and Transients Infrared Camera (RATIR; www.ratir.org) on the 1.5m
Harold Johnson Telescope at the Observatorio Astron��mico Nacional on Sierra San
Pedro M��rtir from 2016/01 19.36 to 2016/01 19.54 UTC (5.61 to 9.76 hours after
the BAT trigger), obtaining a total of 3.20 hours exposure in the r, i, and z bands.
We identified the source reported by Malesani et al., GCN 18895.
In comparison with the SDSS DR9 and 2MASS catalogs, we obtain the
following detections and upper limits (3-sigma):
r 23.78 +/- 0.28
i 23.26 +/- 0.17
z > 20.78
These magnitudes are in the AB system and are not corrected for Galactic
extinction in the direction of the GRB. We thank the staff of the Observatorio
Astron��mico Nacional in San Pedro M��rtir.
