"Alaska's Skies Illuminate with HAARP's Artificial Airglow"

The High-frequency Active Auroral Research Program (HAARP) will conduct a four-day research campaign in Alaska, during which an artificial airglow may be visible in the sky. Scientists from multiple universities will investigate ionosphere mechanisms, plasma waves, and satellite collision detection. The airglow, created by exciting electrons in the ionosphere, will appear as a faint red or green patch and can be seen up to 300 miles from the HAARP facility. HAARP's research aims to explore Earth's upper atmosphere and geospace environment.
