TITLE: GCN CIRCULAR NUMBER: 16965 SUBJECT: GRB 141026A: Continued RATIR Optical and NIR Observations DATE: 14/10/27 16:56:57 GMT FROM: Nat Butler at Az State U 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), Antonino Cucchiara (ORAU/GSFC), 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 141026A (Hagen, et al., GCN 16950)) 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 2014/10 27.13 to 2014/10 27.53 UTC (24.48 to 34.08 hours after the BAT trigger), obtaining a total of 4.64 hours exposure in the r, i, and z bands. The optical afterlow (Littlejohns et al., GCN 16952; also Perley et al., GCN 16955, Varela et al., GCN 16953, Gorosabel et al., GCN 16954, Butler, et al., GCN 16962) continues to fade. In comparison with 2MASS, we obtain the following detections and upper limit (3-sigma): r 22.94 +/- 0.16 i 23.16 +/- 0.22 z > 20.1 These magnitudes are in the AB system and are not corrected for Galactic extinction in the direction of the GRB. The source appears to have faded roughly as t^(-0.5) since our last epoch (GCN 16962). We thank the staff of the Observatorio Astronómico Nacional in San Pedro Mártir. Further observations are planned.
