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 129 publicerat klockan 2200Z på 09 May 2002IA. Analys av solfläcksgrupper och solaktivitet från 08-2100Z till 09-2100Z Solar activity was at low levels. Several minor
C-class flares occurred today, the only optically correlated flare
was a C1/Sf flare at 09/0800 UTC, from Region 9937 (S08W11). This
region has undergone a very slight decay in areal coverage of spot
group since yesterday. Region 9934 (S16W32) has continued to show
growth in penumbral coverage although the delta magnetic spot seen
yesterday is no longer evident. Remaining spotted regions were
mostly quiescent today. No new regions were numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low to moderate levels. Region 9934 remains capable of producing
M-class flares.
IIA. Sammanfattning av geofysisk aktivitet 08-2100Z till 09-2100Z
The geomagnetic field was at quiet to unsettled levels. The ACE
satellite indicated the passage of a weak shock (presumed to be the
result of the M1 flare at 07/0346 UTC) at approximately 09/0900 UTC.
The Bz energy channel remained north and several periods of
unsettled conditions persisted.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field activity
is expected to be a quiet to unsettled levels through the forecast
period.
