TITLE: GCN CIRCULAR NUMBER: 14494 SUBJECT: GRB 130427A: CARMA 3mm observations DATE: 13/04/28 22:38:23 GMT FROM: Daniel Perley at Caltech D. A. Perley (Caltech) reports on behalf of a larger collaboration: We observed the position of GRB 130427A (Maselli et al.; GCN 14448) with the Combined Array for Research in Millimeter Astronomy on two epochs on 2013-04-28 (UT), between 01:45 and 02:46 and again between 07:22 and 08:14, at a frequency of 93 GHz (3 mm). The afterglow is well-detected in both epochs. Preliminary reduction gives fluxes of: 3.7 +/- 0.4 mJy (t_mid = 0.769 day) 2.6 +/- 0.4 mJy (t_mid = 1.000 day) These values are consistent with the flux reported by Zauderer et al. (GCN 14482) as also measured by CARMA at a time intermediate between these epochs. The source location is: RA = 11:32:32.82 Dec = +27:41:56.06 (J2000, uncertainty 0.4 arcsec) Further observations are planned. We thank the CARMA staff for their support in executing these observations.
