This experiment was designed to measure the interaction of expanding nuclear weapon debris with the ion-loaded geomagnetic field. Five rockets on Star Fish and two rockets on Check Mate were used to position instrumented payloads at various distances around the burst points. The instruments measured the magnetic field, ion flux, beta flux, gamma flux, and the neutron flux as a function of time and space around detonations. Data was transmitted at both real and recorded times to island receiving sites near the burst regions. Measurements of the telemetry signal strengths at these sites allowed observations of blackout at 250 Mc. Data reduction indicates that the early expansion of the Star Fish debris probably took the form of an ellipsoid with its major axis oriented along the earths magnetic field lines. Collapse of the magnetic bubble was complete in approximately 16 seconds, and patt of the fission fragment beta particles were subsequently injected into trapped orbits.
