We observed the field of GRB 140614B (Page, et al., GCN 16394Not found
 
 
) 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 2014/06 14.28 to 2014/06 14.47 UTC (0.11 to
4.62 hours after the BAT trigger), obtaining a total of 0.71 hours exposure
in the r and i bands and 0.30 hours exposure in the Z, Y, J, and H bands.

For a source within the Swift-XRT error circle, in comparison with 2MASS,
we obtain the following upper limits (3-sigma):

  r     > 22.70
  i     > 22.53
  Z     > 21.64
  Y     > 21.08
  J     > 21.04
  H     > 20.51

These magnitudes are in the AB system and are not corrected for Galactic
extinction in the direction of the GRB.

M��rtir.
