The High-frequency Active Auroral Research Program (HAARP) will be conducting a research campaign from Oct. 19 to Oct. 28, with transmissions taking place between 1400-0600 UTC (see table below for details). Actual transmit days and times are highly variable based on real-time ionospheric conditions. All information is subject to change. This campaign will be the most scientifically diverse ever conducted at HAARP; some particularly notable experiments include a first-of-its-kind attempt to bounce a signal off of Jupiter, investigation into possible causes of the airglow phenomenon known as STEVE (Strong Thermal Emission Velocity Enhancement), and testing the feasibility of using radio transmissions to measure the interiors of near-Earth asteroids. Experiments benefiting from amateur radio support or having citizen science applications are described in the HAARP Letter to the Amateur Radio Community, along with known frequency information. An official HAARP press release is available from the University of Alaska Geophysical Institute.
