We observed the field of GRB 141005A (D'Elia, et al., GCN 16882) 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 2014/10 5.22 to 2014/10 5.27 UTC (0.05
to 1.34 hours after the BAT trigger), obtaining a total of 1.07 hours
exposure in the r and i bands.

We note evidence of the source reported by P60 (Perley, et al., GCN 16884),
with marginal evidence for fading throughout the epoch of RATIR
observations.
Further analysis is ongoing.
