TITLE: GCN CIRCULAR NUMBER: 15301 SUBJECT: GRB 130925A: 3mm observations with CARMA DATE: 13/10/04 16:39:51 GMT FROM: Ashley Zauderer at CfA B. A. Zauderer, E. Berger, T. Laskar (Harvard) report on behalf of a larger collaboration as part of the CARMA Key Project "A Millimeter View of the Transient Universe": "We observed the position of GRB 130925A (Lien et al., GCN 15246) with the Combined Array for Research in Millimeter Astronomy (CARMA) beginning 2013 Sep 26.36 (dt = 1.19 d) at a mean frequency of 93 GHz. Observations were conducted in the compact E configuration, with significant flagging for shadowed antennas required. We do not detect any significant radio emission to a 3-sigma limit of 0.6 mJy at the position of the Swift-XRT position (Evans et al., GCN 15251). We thank the CARMA observers and staff for prompt execution of these observations."
