  GRB 070724B is the first Gamma Ray Burst localized by SuperAGILE, the hard
X-ray monitor aboard the AGILE satellite. The coordinates of the event were
published $\sim 19$ hours after the trigger. The Swift X-Ray Telescope pointed
at the SuperAGILE location and detected the X-ray afterglow inside the
SuperAGILE error circle. The AGILE gamma-ray Tracker and Minicalorimeter did
not detect any significant gamma ray emission associated with GRB 070724B in
the MeV and GeV range, neither prompt nor delayed. Searches of the optical
afterglow were performed by the Swift UVOT and the Palomar automated 60-inch
telescopes without any significant detection. Similarly the Very Large Array
did not detect a radio afterglow. This is the first GRB event with a firm upper
limit in the 100 MeV -- 30 GeV energy range, associated with an X-ray
afterglow.
