We observed the field of GRB 160313A (D'Ai, et al., GCN 19171) 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 2016/03 13.14 to 2016/03 13.22 UTC (0.63
to 2.67 hours after the BAT trigger), obtaining a total of 1.42 hours
exposure in the r and i bands and 0.52 hours exposure in the Z,
Y, J, and H bands.
For a source within the Swift-XRT error circle, in comparison with the
SDSS DR9 and 2MASS catalogs, we obtain the following upper limits (3-sigma):
r > 23.49
i > 23.21
Z > 22.08
Y > 21.48
J > 20.11
H > 20.60
These magnitudes are in the AB system and are not corrected for Galactic
extinction in the direction of the GRB. Further observations are planned.

M��rtir.
