>>
>>
>> ACTIVATION: EFFECTIVE IMMEDIATELY
>>VALID UNTIL: 19:00 UTC ON 23 JANUARY
>>
>> HIGH RISK PERIOD: 23 JANUARY (UTC days)
>>MODERATE RISK PERIOD: 22-23 JANUARY
>>
>>PREDICTED ACTIVITY INDICES: 30, 15, 10, 10 (23 JANUARY - 26 JANUARY)
>>
>>POTENTIAL MAGNITUDE OF MIDDLE LATITUDE AURORAL ACTIVITY: MODERATE
>>
>>ESTIMATED OPTIMUM OBSERVING CONDITIONS: NEAR AND AFTER LOCAL MIDNIGHT
>>
>>EXPECTED LUNAR INTERFERENCE: LOW
>>
>>OVERALL OPPORTUNITY FOR OBSERVATIONS FROM MIDDLE LATITUDES: FAIR - GOOD
>>
>>AURORAL ACTIVITY MAY BE OBSERVED APPROXIMATELY NORTH OF A LINE FROM...
>>
>> SOUTHERN-CENTRAL BRITISH COLUMBIA TO SOUTHERN MONTANA TO SOUTH
>>DAKOTA
>> TO SOUTHERN MINNESOTA TO WISCONSIN TO SOUTHERN MICHIGAN TO DARK
>>SKY
>> SITES OF NEW YORK STATE AND SOUTHERN MAINE.
>>
>>ACTIVITY MAY ALSO BE OBSERVED APPROXIMATELY NORTH OF A LINE FROM...
>>
>> EXTREME NORTHERN UNITED KINGDOM TO EXTREME NORTHERN EUROPE
>>INCLUDING
>> MUCH OF NORWAY, CENTRAL TO NORTHERN SWEDEN AND CENTRAL TO
>>NORTHERN
>> FINLAND, TO NORTHERN RUSSIA. EXTREME SOUTHERN REGIONS OF NEW

>> AND POSSIBLY EXTREME SOUTHERN REGIONS OF AUSTRALIA MAY ALSO SPOT
>> PERIODS OF ACTIVITY.
>>
>>
>>SYNOPSIS...
>>
>> Conditions are not yet favorable for widespread observations of
>auroral
>>activity, but may become favorable over the next 6 to 12 hours. An
>unexpected
>>solar disturbance arrived near 20:30 UTC on 22 January. The magnetic fields
>>within the disturbance are currently holding the activation of auroral
>>activity at bay. However, should the fields rotate from the current
>strongly
>>northward orientation to a strong southward direction (which may be
>observed
>>sometime in the next 6 to 12 hours), auroral activity could intensify
>>substantially and provide fairly widespread observations of auroral
>activity
>>from middle latitude dark-sky sites.
>>
>> User's of the Ge+lert software will be able to monitor current auroral
>>activity conditions much more accurately and in near-realtime. Consult:
>>http://solar.uleth.ca/solar/www/geolert.html for details on this
>software.
