The following is a press release from the High-frequency Active Auroral Research Program at the University of Alaska Fairbanks:
The High-frequency Active Auroral Research Program (HAARP) will be conducting a research
campaign August 25-27 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 due to the number of experiments and the need to make real-time schedule 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 from funded investigators, but reception reports are appreciated and may
be submitted to our online form at https://haarp.gi.alaska.edu/form/reception-reports.
