Abstract:

At 0659 GMT March 7, 1972 a shaped barium charge was released high above central Alaska by the Los Alamos Scientific Laboratory and the University of Alaska. In support of this experiment, known as OOSIK, Stanford Research Institute operated two existing radar facilities in Alaska. In addition, a low- frequency receiving site was established and operated near the down-field intercept of the barium release. A preliminary analysis of the data indicates that a magnetic substorm began 17 minutes after the injection and was accompanied by considerable auroral activity. A number of factors suggest that the substorm was not triggered by the barium injection but was of natural origin. If a magnetospheric instability was later triggered by the barium release its effects were masked by the natural event.
