Collaboration:
"We observed the field centered on the BAT position of the Swift short
hard burst GRB 070923 (GCN#6818) using the VLA at a frequency of 8.46 GHz
and starting at 18.70 UT on Sept 28, 2007, about 5 days after the burst.
There is no detection of the afterglow at the GRB Swift-BAT position
(GCN#6821 )with 2-sigma upper limit of 90 microJy on its flux density.
