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 262 publicerat klockan 2200Z på 18 SEP 2000IA. Analys av solfläcksgrupper och solaktivitet från 17-2100Z till 18-2100Z SOLAR ACTIVITY WAS LOW. A NUMBER OF C-CLASS SUBFLARES
OCCURRED IN REGIONS 9165 (N14W40), 9166 (S14E24), AND 9167 (N12E57).
DECAY IN REGION 9165 HAS SLOWED AND THE AREA RETAINS SOME MAGNETIC
COMPLEXITY. REGION 9166 CONTINUES TO GROW SLOWLY AND IS PRESENTLY AN
E-TYPE SUNSPOT GROUP WITH SOME MIXED POLARITIES. NEW REGION 9169
(N08E70) IS A LARGE SUNSPOT GROUP ROTATING AROUND THE EAST LIMB, AND
IS ABUTTED TO THE SOUTHEAST OF REGION 9167. SO FAR IT HAS NOT
PRODUCED SIGNIFICANT FLARES BUT IT APPEARS TO BE A CAPABLE REGION;
HOWEVER, ITS LIMB PROXIMITY MAKES ANALYSIS DIFFICULT.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. FLARE ACTIVITY IS EXPECTED FROM REGIONS 9165, 9166,
9167, AND 9169.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 17/2100Z TO 18/2100Z:
THE GEOMAGNETIC FIELD RANGED FROM ACTIVE TO MAJOR STORM LEVELS AT
MIDDLE LATITUDES AND ACTIVE TO SEVERE STORM LEVELS AT HIGH
LATITUDES. THE MOST DISTURBED PERIOD OCCURRED FROM 17/2100 UTC TO
18/0300 UTC. THE GEOMAGNETIC FIELD APPEARS TO BE UNDER THE INFLUENCE
OF A HIGH-SPEED CORONAL HOLE STREAM, PUNCTUATED WITH THE PASSAGE OF
CME MATERIAL. THE MOST DISTURBED PERIOD WAS ASSOCIATED WITH A CME.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE AT ACTIVE TO STORM LEVELS. THE HIGH-SPEED STREAM IS
EXPECTED TO PERSIST AND ANOTHER CME IS EXPECTED TO ARRIVE EITHER
LATE ON SEP 18 OR EARLY ON SEP 19.
