🌌 Hearing something odd between 2.8 and 10 MHz this week? It might be HAARP.
The High-frequency Active Auroral Research Program is mid-campaign — running through Friday 11 September (UTC) — transmitting from its antenna array at Gakona, Alaska. Thursday's window is the next to watch: 12:00–16:00 UTC (13:00–17:00 BST), morning listening hours on both sides of the Atlantic.
What you'll hear is unlike anything else on the bands. HAARP transmits on authorised frequencies between 2.8 and 10 MHz — sometimes steady carriers, sometimes sweeping or modulated signals that appear and vanish, because the experiments constantly retune to follow ionospheric conditions. If a mysterious, oddly powerful signal drifts past your dial this week, check the schedule before you log it as an intruder.
The timing is genuinely interesting for anyone chasing propagation science: this has been a disturbed week.
Tuesday delivered two minor geomagnetic storms, and more storm activity has returned to the forecast. An active, stirred-up auroral ionosphere is exactly the laboratory HAARP studies best.
Hearing Gakona under disturbed conditions tells you something about the ionosphere you can't read from a propagation forecast.
HAARP actively invites reception reports — hams and SWLs alike — via their online form: https://haarp.gi.alaska.edu/form/reception-reports
One rule: report what you actually hear, never guess a frequency in advance — no specific frequencies are published, only the authorised band. And if you miss Thursday, one final window follows Friday 02:00–07:00 UTC — all subject to change at short notice.
Will you be tuning the low bands this week — and have you ever logged HAARP before? 🎧
