report:
We observed the field of GRB 161011A (D'Elia, et al., GCN 20023) 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 2016/10 13.11 to 2016/10 13.15 UTC (44.66
to 45.69 hours after the BAT trigger), obtaining a total of 0.69 hours
exposure in the r and i bands and 0.27 hours exposure in the Z,
Y, J, and H bands.
We do not detect the optical source reported by Mazaeva, et al. (GCN 20030).
For a source within the Swift-XRT error circle (Osborne, et al., GCN 20026),
in comparison with the SDSS DR9 and 2MASS catalogs, we obtain the following
detections and upper limits (3-sigma):
r > 23.4
i > 22.7
Z > 21.7
Y > 21.4
J > 21.0
H > 20.7
These magnitudes are in the AB system and are not corrected for Galactic
extinction in the direction of the GRB.
