TITLE: GCN CIRCULAR NUMBER: 14979 SUBJECT: GRB 130702A: CARMA 3mm detection DATE: 13/07/04 06:15:19 GMT FROM: Daniel Perley at Caltech D. A. Perley (Caltech) and M. Kasliwal (Carnegie) report on behalf of a larger collaboration: We observed the location of the probable optical counterpart of Fermi GRB 130702A (Singer et al., GCN 14967; Cheung et al., GCN 14971; Collazzi & Connaughton, GCN 14972) with the Combined Array for Research in Millimeter Astronomy (CARMA) on 2013-07-04 between 00:28:21 and 05:56:31 UT, 2.01-2.24 days after the GBM trigger, at a frequency of 93 GHz (3 mm). Weather conditions were poor initially but improved somewhat over the course of the integration. In a preliminary reduction of the data we detect a millimeter source coincident with the location of the optical counterpart with a flux of approximately ~2 mJy. We thank John Carpenter and the CARMA staff for their support.
