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 125 publicerat klockan 2200Z på 05 May 2010IA. Analys av solfläcksgrupper och solaktivitet från 04-2100Z till 05-2100Z Solar activity increased to moderate levels. Region
1069 (N41W40) produced an M1/Sf flare at 05/1719Z and a C8 flare at
05/1152Z, as well as occasional lesser B- and C-class flares. Region
1069 gradually increased in area and maintained a beta-gamma
magnetic configuration. Region 1066 (S26W22) produced a B4 flare at
05/1618Z associated with an EIT-wave/dimming event. New Region 1070
(N21W08), a small simple B-type spot group, was assigned late in the
period.
IB. Prognos för solaktivitet
Solar activity is expected to be low
during days 1 - 3 (06 - 08 May) with a chance for isolated M-class
flares from Region 1069.
IIA. Sammanfattning av geofysisk aktivitet 04-2100Z till 05-2100Z
Geomagnetic field activity was at quiet to (briefly) unsettled
levels. ACE solar wind measurements indicated Earth remained within
a subsiding coronal hole high-speed stream. Velocities gradually
decreased from 620 to 538 km/sec during the summary period. The
greater than 2 MeV electron flux at geosynchronous orbit reached
high levels during the past 24 hours.
IIB. Prognos för geofysisk aktivitet
Geomagnetic field activity is
expected to be at mostly quiet levels during days 1 - 2 (06 - 07
May) as the coronal hole high-speed stream continues to subside.
Field activity is expected to increase to unsettled levels on day 3
(08 May) in response to the B4 wave/dimming event mentioned above.
