Alaskans and guests might be able to see a synthetic airglow within the sky created by the Excessive-frequency Lively Auroral Analysis Program throughout a four-day analysis marketing campaign that begins Saturday.
Scientists from the College of Alaska Fairbanks, Cornell College, College of Colorado Denver, College of Florida and Georgia Institute of Know-how will conduct quite a lot of experiments on the UAF-operated analysis website.
The experiments will concentrate on the ionosphere, the area of the environment between about 30 and 350 miles above the Earth’s floor.
Scientists will examine ionosphere mechanisms that trigger optical emissions. They will additionally attempt to perceive whether or not sure plasma waves—fuel so sizzling that electrons get knocked off atoms—amplify different very low frequency waves. And so they’ll examine how satellites can use plasma waves within the ionosphere for collision detection and avoidance.
Every day, the airglow could possibly be seen as much as 300 hundred miles from the HAARP facility in Gakona. The positioning lies about 200 miles northeast of Anchorage and 230 miles southeast of Fairbanks, or about 300 to 350 kilometers.
HAARP creates airglow by thrilling electrons in Earth’s ionosphere, just like how solar energy creates pure aurora, with on and off pulses of high-frequency radio transmissions. HAARP’s Ionospheric Analysis Instrument, a phased array of 180 high-frequency antennas unfold throughout 33 acres, can radiate 3.6 megawatts into the higher environment and ionosphere.
The airglow, if seen, will seem as a faint pink or probably inexperienced patch. Due to the best way the human eye operates, the airglow is perhaps simpler to see when trying simply to the facet.

HAARP will create an airglow at a selected level within the sky. The angle of visibility for anybody desirous to search for it should rely upon an individual’s distance from HAARP.
HAARP transmission frequencies will range however will happen between 2.8 and 10 megahertz. Precise transmit days and occasions are extremely variable based mostly on real-time ionospheric and/or geomagnetic circumstances.
Extra details about the analysis marketing campaign can be accessible on the HAARP website.
The Nationwide Science Basis in 2021 awarded the UAF Geophysical Institute a five-year, $9.3 million grant to ascertain the Subauroral Geophysical Observatory at HAARP. The observatory explores Earth’s upper atmosphere and geospace setting.
The grant has supported a number of HAARP analysis campaigns, together with this one. It additionally helped fund the return to HAARP of the Polar Aeronomy and Radio Science Summer season College, which hosted greater than 50 researchers in August.
The Air Drive initially developed and owned HAARP however transferred the analysis devices to UAF in August 2015. UAF operates the location beneath an settlement with the Air Drive.
Pilots flying within the Gulkana space are requested to verify with the Federal Aviation Administration for short-term flight restriction particulars.
