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 126 publicerat klockan 2200Z på 06 May 2005IA. Analys av solfläcksgrupper och solaktivitet från 05-2100Z till 06-2100Z Solar activity was moderate. Region 756 (S08W79)
produced an M1 x-ray flare at 06/1128 UTC. This region continues to
slowly decay. Region 758 (S07E23) generated a more significant
flare, a C8/2f at 06/1705 UTC. Although smaller in x-ray output,
this flare was of long-duration and associated with a type II sweep
and an apparent Earth-directed CME. Both of these regions also
produced smaller flares over the past 24 hours.
IB. Prognos för solaktivitet
Solar activity is expected to be low
to moderate. C-class activity is expected in Regions 756 and 758.
Another small M-class flare is possible.
IIA. Sammanfattning av geofysisk aktivitet 05-2100Z till 06-2100Z
The geomagnetic field was quiet to unsettled. A small Sudden Impulse
(8 nT) was observed by the Boulder magnetometer at 08/1306 UTC. The
greater than 2 MeV electron flux at geosynchronous orbit was high.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet to unsettled for the next 24 hours. Increased
activity is possible on 08 and 09 May in response to the CME
discussed in Part IA. The field may also be affected by a coronal
hole high speed stream beginning on 09 May.
