"The precipitating electrons that cause the green picket fence are thus aurora, though this occurs outside the
auroral zone, so it's indeed unique."
Ian Griffin, director of the Otago Museum in New Zealand, shared snippets of his experience on Twitter saying, 'Nice trip through the southern
auroral zone tonight on Flight To the Lights.
The images revealed that "there are different kinds of irregularities in the
auroral zone compared to the polar cap," according to coauthor Anthony Mannucci, such that "the effects on radio signals will be different in these two locations." Specifically, the disturbances in the auroral region were larger in scale (about 1-40 kilometers in diameter) than those over the Arctic polar cap (about 1-8 kilometers in diameter).
Geomagnetically he is closer to the
auroral zone than the United Kingdom and is much better placed to ob serve this phenomenon.
Satellites and ground-based radars reveal that there is a surprising outflow of ionized oxygen atoms from the
auroral zone into space.
They believe this radiation is closely related to the soft radiation previously detected during rocket flights in the
auroral zone....
During the environmental study early in the progress of the HAARP project, Gakona, Alaska, was identified as a DOD-owned location within the Arctic
auroral zone. The Gakona site had been planned by the USAF to be an Over the Horizon Backscatter (OTH-H) radar installation.
Three bright areas dominate the dayside

Those interested in aurorae and related phenomena should access the American website www.spaceweather.com for up to the minute information, and a gallery of exquisite photographs from the
Auroral Zone. And if it looks promising, find a clear northern outlook and hope for the best.
