TITLE: GCN CIRCULAR NUMBER: 15783 SUBJECT: GRB 140129A: 5 GHz VLA observations DATE: 14/02/05 15:41:46 GMT FROM: Alessandra Corsi at GWU A. Corsi (GWU) reports on behalf of a larger collaboration: We observed the field of the Swift GRB 140129A (Melandri et al., GCN #15760) using the the Karl G. Jansky Very Large Array (VLA) in C-band, and starting at 00:57:45 UT on 30 Jan 2014. A provisional reduction shows no radio emission above the 3-sigma level of 30uJy (the map rms is ~10uJy at 5 GHz) within the Swift XRT error-circle (Evans et al. GCN #15764). The flux density at the P60 optical afterglow position (Perley & Cenko, GCN #15761) is -8 +/-10 uJy at 5 GHz. We thank the VLA staff for executing these observations.
