AURORAL ACTIVITY *MAY* BE OBSERVED APPROXIMATELY NORTH OF A LINE FROM...

SOUTHERN BRITISH COLUMBIA TO NORTHERN MONTANA TO NORTH DAKOTA TO MINNESOTA

TO NORTHERN WISCONSIN / MICHIGAN TO SOUTHERN CANADA AND POSSIBLY SOME DARK

SKY SITES OF THE EXTREME NORTHEASTERN U.S.

SYNOPSIS...

A moderately vigorous interplanetary disturbance (thought to be related
to a recent full halo coronal mass ejection) impacted the ACE spacecraft near
09:15 UTC on 06 November. Over the last few hours, conditions have become
increasingly favorable for periods of potentially strong auroral storming.
The most favorable regions to observe activity are expected to be the
northern European regions. Activity will probably be on the decline by the
time North America and New Zealand/Australia re-enters darkness.

Lunar interference will be moderately strong until after the moon sets
(near 1 am local time). Thereafter, optimal dark sky conditions should exist
for many favorably located northern European regions.

Observers interested in monitoring auroral activity conditions and being
alerted in real-time to potential visible levels of auroral activity are
encouraged to investigate the software available at:

This warning will remain in effect until 19:00 UTC on 07 November. It
will then be updated or allowed to expire. For more up-to-date information,
