Perley (Caltech) reports on behalf of a larger collaboration: We observed the position of GRB 140129A (Melandri et al., GCN 15760) with the Combined Array for Research in Millimeter Astronomy starting at 04:57:21 UT, 94 minutes after the GRB trigger. Observations continued until 06:10:30 UT (source elevation = 19 degrees). No source is detected at the optical afterglow location to a limiting flux of <1.8 mJy (3 sigma). We thank C. Hull, N. Volgneau, and the CARMA staff for this rapid observation.
