TITLE: GCN CIRCULAR NUMBER: 15566 SUBJECT: GRB 131202A: RATIR Optical and NIR Observations DATE: 13/12/03 04:32:41 GMT FROM: Antonino Cucchiara at UCSC/UCO Lick A. Cucchiara (ORAU/GSFC), Nat Butler (ASU), Alan M. Watson (UNAM), Alexander Kutyrev (GSFC), William H. Lee (UNAM), Michael G. Richer (UNAM), Chris Klein (UCB), Ori Fox (UCB), J. Xavier Prochaska (UCSC), Josh Bloom (UCB), Eleonora Troja (GSFC), Owen Littlejohns (ASU), Enrico Ramirez-Ruiz (UCSC), Jos�� A. de Diego (UNAM), Leonid Georgiev (UNAM), Jes��s Gonz��lez (UNAM), Carlos Rom��n-Z����iga (UNAM), Neil Gehrels (GSFC), and Harvey Moseley (GSFC) report: We observed the field of GRB 131202A (Kocevski, et al., GCN 15559) 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 2013/12 3.08 to 2013/12 3.15 UTC (10.81 to 12.32 hours after the BAT trigger), obtaining a total of 1.04 hours exposure in the r and i bands and 0.44 hours exposure in the Z, Y, J, and H bands. For a source within the Swift-XRT error circle, in comparison with 2MASS, we obtain the following upper limits (3-sigma): r > 22.99 i > 22.56 Z > 21.50 Y > 20.68 J > 20.43 H > 20.05 These magnitudes are in the AB system and are not corrected for Galactic extinction in the direction of the GRB. We thank the staff of the Observatorio Astron��mico Nacional in San Pedro M��rtir.
