Päikese aktiivsuse aruanne
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Ühine USAF / NOAA päikese- ja geofüüsikaalase aktiivsuse aruanne
SDF number 326 Välja antud 2200Z kuni 22 NOV 1998IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 21-2100Z kuni 22-2100Z SOLAR ACTIVITY INCREASED TO HIGH LEVELS. REGION 8384
(S26W88) PRODUCED TWO X-CLASS FLARES AS IT CROSSED THE WEST LIMB.
THE FIRST WAS AN X3/1N AT 22/0642UT WITH AN ASSOCIATED 340 SFU
TENFLARE, A SIGNIFICANT TYPE II RADIO SWEEP, A MINOR TYPE IV RADIO
SWEEP AND MODERATE DISCRETE RADIO BURSTS. THE SECOND FLARE WAS AN
X2/2N AT 22/1623UT WITH AN ASSOCIATED LOOP PROMINENCE SYSTEM AND
MODERATE DISCRETE RADIO BURSTS. THIS SUDDEN INCREASE TO HIGH LEVELS
WAS SURPRISING GIVEN THE STABILITY EXHIBITED BY REGION 8384 DURING
RECENT DAYS. A OPTICALLY UNCORRELATED M1 X-RAY FLARE OCCURRED AT
22/1839UT. THE REMAINING REGIONS APPEARED STABLE. NO NEW REGIONS
WERE NUMBERED.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE AT
MODERATE TO HIGH LEVELS DURING THE FIRST DAY. REGION 8384 APPEARS
CAPABLE OF ADDITIONAL MAJOR FLARE ACTIVITY AS IT CONTINUES TO ROTATE
OUT OF VIEW. ACTIVITY IS EXPECTED TO DECLINE TO LOW TO MODERATE
LEVELS DURING THE REST OF THE PERIOD.
IIA. Summaarne geofüüsikaline aktiivsus 21-2100Z kuni 22-2100Z
THE GEOMAGNETIC FIELD WAS AT QUIET TO UNSETTLED LEVELS. A SOLAR
PROTON FLUX ENHANCEMENT WAS DETECTED AT GEOSYNCHONOUS ALTITUDE
FOLLOWING TODAY'S X3/1N FLARE. THE GT 100 MEV PROTON FLUX BECAME
ENHANCED AROUND 22/0700UT, THEN RETURNED TO BACKGROUND LEVELS BY
22/1200UT. THE GT 10 MEV PROTON FLUX BECAME ENHANCED AROUND
22/0800UT AND WAS GRADUALLY DECLINING TOWARD BACKGROUND LEVELS AT
THE END OF THE REPORTING PERIOD.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED TO ACTIVE THROUGHOUT THE PERIOD. THE GT 10
MEV PROTON FLUX ENHANCEMENT IS EXPECTED TO RETURN TO BACKGROUND
LEVELS DURING THE FIRST DAY, BARRING ANOTHER PROTON FLARE FROM
REGION 8384.
