G. Petitpas (SAO), A. Zauderer, T. Laskar, E. Berger (Harvard) report
on behalf of the SMA Rapid Transients (SMART) Key Project:
"We observed the position of GRB 120907A (Racusin et al; GCN 13716)
with the Submillimeter Array (SMA) beginning 2012 Sep 7.63 UT (dt ~ 0.6
d). At a mean frequency of 230 GHz, we do not detect significant radio
emission within the enhanced Swift/XRT error circle (Goad et al; GCN
13702) to a 3-sigma upper limit of 2.7 mJy. Beginning 2012 Sep 8.5 UT
(dt ~ 1.5 d), we repeated our observations, and report a 3-sigma upper
limit of 2.4 mJy.
We thank the SMA Observatory staff for its support."
