We observed the field of GRB 160203A (D'Avanzo, et al., GCN 18979) 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 2016/02 6.28 to 2016/02 6.52 UTC (76.40 to
82.32 hours after the BAT trigger), obtaining a total of 4.27
hours exposure in the r, i, and z bands.
For a source within the Swift-XRT error circle (Osborne, et al.,
GCN 18983), in comparison with the USNO-B1 and 2MASS catalogs, we obtain
the following upper limits (3-sigma):
r > 24.20
i > 24.14
z > 19.92
These magnitudes are in the AB system and are not corrected for Galactic
extinction in the direction of the GRB.
