TITLE: GCN CIRCULAR NUMBER: 14482 SUBJECT: GRB 130427A: CARMA 85 GHz detection DATE: 13/04/28 05:22:11 GMT FROM: Ashley Zauderer at CfA B. A. Zauderer, E. Berger, S. Chakraborti, and A. M. Soderberg (Harvard) report on behalf of the CARMA Key Project "A Millimeter View of the Transient Universe": "We began observing the field of GRB 130427A (Maselli et al.; GCN 14448) with the Combined Array for Research in Millimeter Astronomy on 2013 Apr 28.13 UT (dt ~ 0.8 d). In 45 minutes integration on source at a mean frequency of 85 GHz, we detect a radio counterpart with a preliminary flux of ~3 mJy (>10-sigma) at a position consistent with the reported optical afterglow (Elenin et al., Perley et al.; GCNs 14450, 14451) and our VLA 5 GHz detection (Zauderer et al.; GCN 14480). Observations are ongoing. We thank the CARMA observers and the observatory staff for their support."
