The High-frequency Active Auroral Research Program (HAARP) will be conducting a research campaign November 4-7 to study artificial airglow and very low freqency/extremely low frequency (VLF/ELF) radio waves. The primary goals of this research campaign are to better understand the mechanisms in the ionosphere that produce optical emissions, and to investigate if certain types of waves in the ionosphere can amplify VLF/ELF waves. Additional experiments seek to determine if satellites can use plasma waves in the ionosphere for collision detection and avoidance.
