SYNOPSIS...
Effects of a well placed solar coronal hole possibly combined with
effects of a coronal mass ejection associated with a filament eruption a few
days ago are expected to produce periods of enhanced solar wind conditions
capable of producing periods of moderately strong auroral substorm activity.
Minor to major auroral substorming is possible over the high latitudes during
the next 12 hours.
Effects of todays major X-class solar flare have not been included in
this assessment. The data associated with this event will be analyzed
separately and may warrant extending this watch. Details may follow in an
update to this watch if deemed necessary.
This watch will remain valid through 23:00 UTC (6 pm EST) on
19 March. It will then be updated or allowed to expire.
PLEASE REPORT OBSERVATIONS OF AURORAL ACTIVITY TO:
http://www.spacew.com/submitsighting.html
Observations reported here are permanently recorded for future study and
are immediately made available in real-time to a large network of observers
world-wide via the Internet, e-mail and pager. If you observe activity, your
assistance to contribute to this database would be appreciated.
