We observed the field of GRB 130606B (Vianello et al., GCN Circular
14795) 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 2013/06 7.16 to
2013/06 7.25 UTC (15.97 to 18.08 hours after the BAT trigger), obtaining
a total of 0.36 hours exposure in the r' and i' bands and 0.30 hours
exposure in the Y and H bands.
For a source within the XRT error circle (Kennea et al., GCN Circular
14820), in comparison with USNO-B1 and 2MASS, we obtain the following
3-sigma upper limits:
r' > 23.59
i' > 23.61
Y > 21.52
H > 20.73
These magnitudes are in the AB system and not corrected for Galactic
extinction in the direction of the GRB.
No further observations are planned.
