Abstract:

During this contract period, the work performed at the HIPAS site can be divided into two categories. The first category is basic site maintenance and the second category is experimental and scientific endeavors. The harsh weather at the HIPAS site combined with the remote location greatly increase the sight maintenance requirements. There are further complicated by interference from animals and providing the security necessary to preserve the facilities. On the experimental program the large backlog of data from the Gilmore Creek site has begun to be analyzed. This data indicates that we can detect ELF signals 11-100 Hz 18 miles away. The ELF is generated by interaction of the HIPAS 2.8 MHz radio bean and the polar electroject. The signals were detected by a three axis Schumann Receivers developed by Dave Sentman of UCLAs Institute of Geophysics and Planetary Physics. The received data has been stored on optical disks and tapes. Similar ELF data has been recorded at Table Mountain, California, as well as at a new station at Northwest Cape Australia, which was able to detect the HIPAS signal.
