Xavier Prochaska (UCSC), Josh Bloom (UCB), Antonino Cucchiara (UCSC), Eleonora Troja (GSFC), 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 130305A (Cummings, et al., GCN 14257) 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 2013/03 6.12 to 2013/03 6.13 UTC (15.11 to 15.50 hours after the BAT trigger), obtaining a total of 0.31 hours exposure in the r' and i' bands. For a source within the Swift-XRT error circle (Malesani, et al., GCN 14263), in comparison with USNO-B1, we derive the following upper limits (3-sigma) in the AB magnitude system: r' > 23.4 i' > 23.1 These magnitudes are not corrected for Galactic extinction in the direction of the GRB.
