Aurora Forecast for Sunday, September 14, 2014

Active: 0 1 2 3 4 5 6 7 8 9

Forecast: Auroral activity will be active. Weather permitting, active auroral displays will be visible overhead from Barrow to Anchorage and Juneau, and visible low on the horizon from King Salmon and Prince Rupert.

Forecaster Comments: The effects of a solar event on the 9th of September facing roughly toward Earth should reach Earth around midnight on September 11th UT. Another, larger event occurred on September 10th that should have higher velocity. The effects from the latter event may reach Earth at the same time. Even if it is later, disturbances should be large and last long enough to result in increased auroral activity anytime for three or four days. The result is that aurora watchers should watch
for the next five to seven days. We will post more accurate predictions when the observations of the solar activity have been analyzed.
