behalf of the Caltech-NRAO-Carnegie GRB Collaboration:
"We used the Very Large Array to observe the field of view toward
GRB 090401B (GCN 9066) at a frequency of 8.46 GHz on 2009 Apr. 02.15
UT. The GRB radio afterglow is undetected at the Swift-UVOT position
(GCN 9067). The three-sigma flux density of the GRB afterglow at the
Swift UVOT position is 138 uJy.
