D. A. Perley (Caltech) reports on behalf of a larger collaboration:
We observed the location of GRB 140419A (Marshall et al., GCN 16118)
with the Combined Array for Research in Millimeter Astronomy at a mean
frequency of 93 GHz starting at 05:23:45, 77 minutes after the GRB
trigger.
In the first hour of observations, we marginally detect a weak source
consistent with the location of the optical afterglow (Zheng et al., GCN
16119; Guver et al., GCN 16120) with a flux of approximately 1.5 mJy.
Observations are continuing.
We thank J. Carpenter and D. Segura-Cox for assistance with rapidly
scheduling and executing the observations.
