Notice: Upcoming HAARP ionospheric tests from Alaska – 8th to 10th May 2024

Reporting on radio science and experiments

High-frequency Active Auroral Research Program (HAARP) is based in Alaska and it’s a high-power, high frequency (HF) transmitter for studying the ionosphere.  The principal instrument is a phased array of 180 HF crossed-dipole antennas  capable of radiating 3.6 megawatts  into the upper atmosphere and ionosphere.  Transmit frequencies are selectable in the range of 2.7 to 10 MHz.

The research team have announced that they will be carrying out tests from the 8th to the 10th of May 2024.

The press release is shown below and I’ve added a map to show location and distance.

The High-frequency Active Auroral Research Program (HAARP) will be conducting a research campaign May 8-10 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.
