The following is a message from the HAARP Program Office:
The High-frequency Active Auroral Research Program (HAARP) will be conducting a research campaign September 8 – 11 UTC, with operating times specified in the table below. Operating frequencies will vary, but all HAARP transmissions will be between 2.8 MHz and 10 MHz. Actual transmit days and times are highly variable based on real-time ionospheric and/or geomagnetic conditions. All information is subject to change.
Note that, because the experiments generally require real-time schedule and frequency adjustments based on ionospheric conditions, no frequencies are specified in the table below. The included transmission notice supplement contains information on the frequencies HAARP is authorized to transmit. HAARP transmissions will only occur on our authorized frequencies. There are no specific data collection requests by investigators, but reception reports are appreciated and may be submitted to our online form at https://haarp.gi.alaska.edu/form/reception-reports.
