We observed the field of GRB 131202A (Kocevski, et al., GCN 15559) with 
Reionization and Transients Infrared Camera (RATIR; on 
1.5m Harold Johnson Telescope at the Observatorio Astron��mico Nacional 
Sierra San Pedro M��rtir from 2013/12 3.08 to 2013/12 3.15 UTC (10.81
to 12.32 hours after the BAT trigger), obtaining a total of 1.04 hours
exposure in the r and i bands and 0.44 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	> 22.99
   i	> 22.56
   Z	> 21.50
   Y	> 20.68
   J	> 20.43
   H	> 20.05

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