Dual-frequency observations of lunar meteoroid-strike EMPs.

Passive observations of the first-quarter moon at 327 MHz and S-band are proposed to search for possible ElectroMagnetic Pulses (EMPs) generated by gram-class meteoroid strikes. These EMPs are expected to be approximately 1 microsecond in duration and to occur several times per minute over the lunar surface. If detected, these EMPs would provide insight into the physics of solid-body hypervelocity impacts including how energy is partitioned among the ejecta, plasma, and radiative processes. A total of four observing periods is requested in which we will evaluate the direct and reflected (moon-bounce) interference environment at the two observing frequencies as well as search for EMPs.
