Solaktivitetsrapport
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.

USAF/NOAA rapport för sol- och geofysisk aktivitet
SDF Nummer 171 publicerat klockan 2200Z på 20 JUN 1999IA. Analys av solfläcksgrupper och solaktivitet från 19-2100Z till 20-2100Z SOLAR ACTIVITY BECAME MODERATE. REGION 8592 (N22E64)
PRODUCED AN M2/SB AT 20/1535Z. A DISAPPEARING FILAMENT AND MINOR
CENTIMETRIC RADIO BURSTS ACCOMPANIED THIS EVENT. THIS REGION ALSO
PRODUCED A LONG DURATION C5/SF AT 20/2007Z WITH A LARGE BRIGHT SURGE
TO 1.14R. REGION 8592 APPEARS TO BE COMPRISED OF SEVERAL REGIONS BUT
FORESHORTENING PREVENTED ACCURATE MAGNETIC SEPARATION. THIS SHOULD
BE POSSIBLE WITH ONE MORE DAY OF ROTATION ONTO THE DISK. ANOTHER
REGION BEGAN TO ROTATE OVER THE NORTHEAST LIMB AT NE14. IT WAS
NUMBERED AS NEW REGION 8594 (N14E85) AND CONSISTED OF A LARGE H
CLASS SPOT. IT IS LIKELY TRAILER SPOTS WILL FOLLOW.
IB. Prognos för solaktivitet
SOLAR ACTIVITY SHOULD BE AT LOW TO
MODERATE LEVELS FOR THE NEXT THREE DAYS. THE REGIONS ROTATING OVER
THE NORTHEAST LIMB POSSESS THE CAPABILITY OF PRODUCING OCCASIONAL
M-CLASS EVENTS. THERE IS A SLIGHT CHANCE OF AN X-CLASS EVENT FROM
THIS AREA.
IIA. Sammanfattning av geofysisk aktivitet 19-2100Z till 20-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO SLIGHTLY UNSETTLED.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD SHOULD
REMAIN QUIET TO SLIGHTLY UNSETTLED FOR THE NEXT THREE DAYS.
