"We have observed the field of GRB 100418A (Marshall et al., GCNC
10612) from SMA in the 345 GHz band starting on April 19th 13:00 UT.
In a preliminary analysis of the data we detect a single source coincident
with the position of the afterglow with a flux density of 20+/-2.4 mJy.

Further observations of this very peculiar source are encouraged."
