Harvey Moseley (GSFC) report:

We observed the field of the short-duration GRB 140516A (Bernardini, et
al., GCN 16285) with the Reionization and Transients Infrared Camera
(RATIR; on the 1.5m Harold Johnson Telescope at the
Observatorio Astron��mico Nacional on Sierra San Pedro M��rtir 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.
