HAARP Exhibit for September 2017 Science Campaign 6/6/2017 Generation of Artificial Periodic Complex sequence involving X- Irregularities for measuring mode CW and pulsed heating aeronomic parameters of the lower intervals interspersed with X- and thermosphere. A second objective O-mode probe pulses. The record will be to extend API observations should be on file. into night observations Simultaneous observations of SEE O-mode heating with 30 minutes at multiple gyroharmonics (2, 3, 4, per gyroharmonic (5 5, 6) to validate or refute recent gyroharmonics proposed). theoretical/modeling predictions Frequency stepping through each for obtaining new possibilities for gyroharmonic in order to see the aeronomy diagnostics. Second full SEE spectral characteristics goal is to attempt to observe a two- for pump above and below plasmon decay type instability. gyroharmonic. Fixed heating power, and beam angle (perhaps 20kHz step). Produce F-region irregularities O-mode on for DT off for ~2 min, with varying heater on time where DT varries between 10 between 10 seconds and 1 minutes seconds and 1 minute in . Mode and observe decay times. will cycle through pulse lengths. Frequency will be just below fof2. Produce F-region irregularities O-mode on for 30 seconds off for with varying heater frequency to 2 mins. Frequency will be stepped change altitude and observe decay through bands that will heat at times. altitudes near the F-peak, down to lower F-region. Steps will require retuning.

Produce F-region irregularities and CW o-mode heating at a frequency observe their effects on satellite to chosen to optimally produce F- ground propagation paths region irregularities, with a few antennas dedicated to generate a probe signal. Sea Scatter - HAARP will run in conjunction with satellite overflights. The objective is to observe HAARP transmissions that scatter from the sea up to the satellites. Transmissions to generate SEE will fill in gaps between satellite overpasses Generation of air glow Provided by Dean M. Karjala HAARP Research Supervisor
