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."
