We observed the field of GRB 141015A (Troja, et al., GCN 16909) 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 2014/10 15.39 to 2014/10 15.53 UTC (0.05
to 3.59 hours after the BAT trigger), obtaining a total of 2.44 hours
exposure in the r and i bands.
For a source within the Swift/XRT error circle (Troja, et al., GCN 16910),
we obtain the following upper limits (3-sigma):
r > 23.07
i > 22.48
These magnitudes are in the AB system and are not corrected for Galactic
extinction in the direction of the GRB.
