Trigger by SuperAGILE on AGILE. Gave the coordinate 19 hours later, then, Swift XRT observed the X-ray afterglow. No signal on radio, optical and high energy observations. Upper limit: 350 keV – 2.8 MeV, 4 × 10^−6 erg cm^−2; above 100MeV, 0.02 ph cm^−2. While EGRET (NOT the upper limit): ~ 0.039 ph cm^−2 for GRB 930131 and ~ 0.015 ph cm^−2 for GRB 940217.

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.
Labels: 1.3 prompt observations, 4.4 high energy
