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."
