We observed the field of the short-duration GRB 130313A (Gompertz, et al.,
GCN 14293) with the Reionization and Transients Infrared Camera (RATIR;
www.ratir.org) on the 1.5m Harold Johnson Telescope at the Observatorio
Astronómico Nacional on Sierra San Pedro Mártir from 2013 March 14.30 to
2013 March 14.52 UTC (14.96 to 20.25 hours after the BAT trigger),
obtaining a total of 3.5 hours exposures in the r' and i' bands and 1.5
hours of exposure in the Z, Y, J, and H bands.
For a source within the Swift-XRT error circle (Osborne et al., GCN 14293;
Gompertz et al., GCN 14305), in comparison with SDSS DR8 and 2MASS, we
derive the following upper limits (3-sigma) in the AB magnitude system:
r' > 23.6
i' > 23.3
Z > 22.3
Y > 22.0
J > 21.8
H > 21.3
These magnitudes are not corrected for Galactic extinction in the direction
of the GRB.
