MIDDLE LATITUDE AURORAL ACTIVITY WARNING
POTENTIAL MAGNITUDE OF MIDDLE LATITUDE AURORAL
ACTIVITY: HIGH
EXPECTED LUNAR INTERFERENCE:
MODERATE AFTER LOCAL MIDNIGHT
A powerful and well-directed solar flare from active solar Region 930
was observed early on December 13. This event has the potential to produce
periods of moderate to strong (possibly even intense) auroral storm activity
on December 14, possibly lingering into December 15. The most intense phase
of activity is likely to occur some hours after the initial impact, which is
currently expected near 07:00 UTC on December 14 (2 am EST on December 14).
The moon will begin to impinge on observations after it rises sometime after
local midnight, so the best observations (if possible) will occur prior to
and near local midnight when the moon is still below the horizon.
Note: This warning will remain valid through 24:00 UTC on December 15.
