Xavier Prochaska (UCSC), Josh Bloom (UCB), Antonino Cucchiara (UCSC), Eleonora Troja (GSFC), Owen Littlejohns (ASU), Enrico Ramirez-Ruiz (UCSC), José A. de Diego (UNAM), Leonid Georgiev (UNAM), Jesús González (UNAM), Carlos Román-Zúñiga (UNAM), Neil Gehrels (GSFC), and Harvey Moseley (GSFC) report: We observed the field of GRB 130609A (Cummings, et al., GCN 14828) 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 2013/06 9.15 to 2013/06 9.23 UTC (0.56 to 2.52 hours after the BAT trigger), obtaining a total of 1.24 hours exposure in the r' and i' bands and 0.60 hours exposure in the Z, Y, J, and H bands. For a source within the Swift-XRT error circle, in comparison with SDSS DR9 and 2MASS, we obtain the following upper limits (3-sigma): r' > 23.34 i' > 23.27 Z > 22.39 Y > 21.91 J > 21.72 H > 21.06 These magnitudes are in the AB system and not corrected for Galactic extinction in the direction of the GRB.
