TITLE: GCN CIRCULAR NUMBER: 14210 SUBJECT: GRB 130215A: CARMA 3mm detection DATE: 13/02/15 06:21:53 GMT FROM: Daniel Perley at Caltech D. A. Perley (Caltech) and G. Keating (UC Berkeley) report on behalf of a larger collaboration: We began observations of the position of GRB 130215A (D'Elia et al., GCN 14204) with the Combined Array for Research in Millimeter Astronomy at a frequency of 93 GHz (3mm) starting at 03:28 UT, 1.95 hours after the burst. Observations continued until 05:03 UT (midpoint t=2.73 hours.) A provisional reduction of the data shows a strong detection of a source consistent with the location of the optical afterglow (Zheng et al., GCN 14205). We estimate a preliminary flux at this time of 2.99 +/- 0.39 mJy. Follow-up observations are planned. We thank the CARMA staff for executing these rapid observations.
