We began observing the field of GRB 140129A (Melandri, et al., GCN 15760) 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 at 2014/01 29.15 (12.6 minutes after the BAT trigger).
For a source within the Swift-XRT error circle, in comparison with the SDSS
DR9 and 2MASS, we obtain the following detections:
Filter mag(T0+0.12.6 minutes) mag(12.6 to 44.4 minutes)
r 18.05 +/- 0.01 18.80 +/- 0.01
i 17.85 +/- 0.02 18.67 +/- 0.02
Z 17.72 +/- 0.03 18.50 +/- 0.03
Y 17.82 +/- 0.04 18.33 +/- 0.03
J 17.65 +/- 0.05 18.35 +/- 0.04
H 17.68 +/- 0.07 18.19 +/- 0.05
These magnitudes are in the AB system and are not corrected for Galactic
extinction in the direction of the GRB.
Further observations are underway.
