TITLE: GCN CIRCULAR NUMBER: 14172 SUBJECT: GRB 130131A: CARMA 3mm Observations DATE: 13/02/01 12:56:17 GMT FROM: Ashley Zauderer at CfA B. A. Zauderer, E. Berger, and T. Laskar (Harvard) report on behalf of the CARMA Key Project "A Millimeter View of the Transient Universe": "We observed the position of GRB 130131A (Grupe et al., GCN 14156) with the Combined Array for Research in Millimeter Astronomy beginning 2013 Feb 1.3 UT (0.7 d post-burst) at a mean frequency of ~85 GHz. Coincident with the Swift-XRT position (Evans et al., GCN 14160) and the VLA 5.8 GHz position (Laskar et al., GCN 14171), we report a preliminary detection of a radio source with a flux of ~0.5 mJy. Further analysis is in progress. We thank the CARMA staff for their support."
