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 149 publicerat klockan 2200Z på 28 MAY 2000IA. Analys av solfläcksgrupper och solaktivitet från 27-2100Z till 28-2100Z SOLAR ACTIVITY WAS LOW. THE LARGEST EVENT WAS A C8
X-RAY BURST AT 28/1018UT AND WAS ASSOCIATED WITH AN H-ALPHA LIMB
EVENT (SURGE/SPRAY) NEAR NW 23. THIS EVENT MOST LIKELY OCCURRED IN
RECENTLY DEPARTED REGION 9002. REGION 9017 (S13E29) REMAINS THE MOST
COMPLEX SUNSPOT GROUP CURRENTLY ON THE VISIBLE DISK. THIS AREA HAS
YET TO PRODUCE SIGNIFICANT ACTIVITY. NEW REGIONS 9021 (N03E18) AND
9022 (S21E67) WERE NUMBERED.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. C-CLASS FLARES ARE PROBABLE AND AN ISOLATED M-CLASS
FLARE IS POSSIBLE. REGION 9017 IS THE MOST LIKELY SOURCE OF
ACTIVITY.
IIA. Sammanfattning av geofysisk aktivitet 27-2100Z till 28-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. THE GREATER THAN 2 MEV
ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT WAS MODERATE TO HIGH.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED BECOMING UNSETTLED TO ACTIVE.
INCREASED ACTIVITY IS POSSIBLE DUE TO FAVORABLY POSITIONED CORONAL
HOLES.
