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 170 publicerat klockan 2200Z på 18 Jun 2004IA. Analys av solfläcksgrupper och solaktivitet från 17-2100Z till 18-2100Z Solar activity has been low. There were two C-class
flares during the past 24 hours, a C1 at 2234 UTC from spotless
plage near S08E55 and a C1 at 1626 UTC from Region 635 (S12E25).
Emerging flux was observed in the trailer portion of 635 and this
has led to the formation of a delta spot. Region 634 (N12E07) was
mostly unchanged and was relatively stable during the past 24 hours.
A small, 10 degree filament near S15E09 disappeared, but there was
no evidence for a coronal mass ejection in the SOHO/LASCO imagery.
IB. Prognos för solaktivitet
Solar activity is expected to be
mostly low, but there is a fair chance for an isolated M-class event
sometime during the next three days given the current growth trend
and increased complexity in Region 635.
IIA. Sammanfattning av geofysisk aktivitet 17-2100Z till 18-2100Z
The geomagnetic field was quiet to unsettled during the past 24
hours.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet to unsettled for the next three days.
