We observed the field of the short-duration GRB 140516A (Bernardini, et
al., GCN 16285) 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 2014/05
17.33 to 2014/05 17.46 UTC (11.41 to 14.56 hours after the BAT trigger),
obtaining a total of 2.13 hours exposure in the r and i bands and 0.89
hours exposure in the Z, Y, J, and H bands.

For a source within the Swift-XRT error circle (Osborne, et al., GCN
16289), in comparison with the SDSS DR9 and 2MASS, we obtain the following
upper limits (3-sigma):

  r     > 23.57
  i     > 23.39
  Z     > 21.70
  Y     > 21.52
  J     > 22.00
  H     > 21.48

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 Astronómico Nacional in San Pedro
Mártir.
