Forecast is for Auroras to be visible probably over the next week or so...
Sky and Telescope
"Region 808 will gradually rotate across the solar disk during the
next two weeks. During that time, if it retains its volatility, it may
produce some serious effects at the Earth. The health of spacecraft may be
compromised if additional extreme events are observed. Power grids may
suffer from induced currents caused by intense geomagnetic storms. Radio
communications may suffer from strong scintillation and absorption. And
large regions of the Earth may be able to spot periods of auroral activity
("northern lights"). Region 808 will be best positioned to inflict
strong impacts on the Earth in approximately another 4 to 5 days, with maximal
effects possible from roughly 11 September through 18 September.
Spacecraft will remain vulnerable to potential strong space radiation storms
through to about 23 September.
University of Alaska:
A very bright solar event took place on September 7th around 5:45 pm
Greenwich Time. It is not directly facing Earth, but the shock wave will combine
with that of an earlier event to produce a significant effect at Earth.
We predict that it will arrive on Sept 9 around 11 am Greenwich Time.
Because it will arrive in the morning in Europe (early morning in the US), its
effects will be seen first in southern New Zealand, Tasmania and Siberia.
Depending on the nature of the shock, there should be aurora visible in southern
scandinavia, Scotland and northern US on the evening of the 9th.
Note that this event could be followed by others of similar magnitude
as the active region (No. 0808) moves westward accross the sun, facing Earth
by theweekend. This could result in aurora for the middle US and Northern
Europe.
Happy hunting!

Spent some time the other night trying to capture some shots of the Northern Lights while visiting my brother in Edmonton. This is by no means even close to what these things were doing. It was like a strobe light show worthy of getting serious neck pains after 2 hours. May not be the greatest shots but will give an idea of what they are like.

Interesting shots. Where were you when you took these? It looks like you were away from the city as there appears to be no light pollution.

It was in Sherwood Park. A smudge east of Edmonton. Surprisingly it was in my brother's back yard in a typical well lit neighborhood. They were directly overhead and it was like someone was blowing strobing smoke into the night sky. Exposure was at f3.5 for 20 second intervals. Had it been out of the city limits, it would have been mind blowing. Come to think of it, surprising how little light pollution there really is. |

This was taken back in November when we had some serious aurora activity. The picture isn't too special, but more the fact that I was only an hour north of Pittsburgh. Aurora that far south are quite rare...
