MIDDLE LATITUDE AURORAL ACTIVITY WATCH
ISSUED: 00:00 UT, 26 JANUARY
/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\
VALID UNTIL: 19:00 UTC ON 27 JANUARY
MODERATE RISK PERIOD: 26 - 28 JANUARY (UT days)
PREDICTED ACTIVITY INDICES FOR NEXT 3 DAYS: 25, 20, 15
(INPUT INTO THE PREDICTIVE AURORA SOFTWARE *)
POTENTIAL MAGNITUDE OF MIDDLE LATITUDE AURORAL ACTIVITY: LOW TO MODERATE
EXPECTED LUNAR INTERFERENCE: LOW
OVERALL OPPORTUNITY FOR OBSERVATIONS FROM MIDDLE LATITUDES: FAIR
AURORAL ACTIVITY MAY BE OBSERVED APPROXIMATELY NORTH OF A LINE FROM...
PRIMARILY EXTREME SOUTHERN CANADA NORTHWARD. A FEW NORTHERN U.S.
LOCATIONS MAY ALSO SPOT SOME ACTIVITY UNDER DARK SKIES OVER THE
CENTRAL TO EASTERN U.S..
ACTIVITY MAY ALSO BE OBSERVED APPROXIMATELY NORTH OF A LINE FROM...
NORTHERN U.K. TO THE NETHERLANDS. THIS IS NOT EXPECTED TO BE A
PARTICULARLY GOOD OPPORTUNITY FOR AREAS OF SOUTHERN AUSTRALIAN AND
NEW ZEALAND.
* Contact: Oler@Rho.Uleth.CA or COler@Solar.Stanford.Edu for more information
regarding the Auroral Activity Prediction and Simulation Software.
SYNOPSIS...
A fair to good opportunity for observing auroral activity will exist
over the next 24 to 48 hours. A well-placed solar coronal hole is
expected to generate the activity. The brunt of activity should occur
on 26 January, but is not expected to be very strong. Most of the
observed auroral activity should be confined to areas north of the U.S./
Canada border. Users of our auroral activity prediction and simulation
software should input values of between 20 and 30 (the target activity
level for 26 January is 25, dropping to 20 and 15 for 27 and 28 Jan.)
for the best contoured maps of predicted auroral visibility. For more
information, contact: Oler@Rho.Uleth.CA, or: COler@Solar.Stanford.Edu.
This WATCH will remain active until 19:00 UT on 27 January when it
will either be updated or allowed to expire.
** End of Watch **
