TITLE: GCN CIRCULAR NUMBER: 15314 SUBJECT: GRB 131004A: CARMA 93 GHz upper limit DATE: 13/10/05 19:11:45 GMT FROM: Ashley Zauderer at CfA B. A. Zauderer, E. Berger, W. Fong (Harvard) report on behalf of a larger collaboration and the CARMA Key Project "A Millimeter View of the Transient Universe": "We observed the position of GRB 131004A (Hagen et al., GCN 15303) with CARMA at a mean frequency of 93 GHz beginning 2013 October 5.04 (dt=3.4 hours). We do not find significant radio emission at the position of the enhanced Swift-XRT and UVOT localizations (Evans et al., GCN 15308; De Pasquale et al., GCN 15313), or the optical afterglow detection (Xu et al., GCN 15304), to a 3-sigma upper limit of ~0.3 mJy. No further radio observations are planned. We thank the CARMA staff for prompt execution of these observations."
