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 094 publicerat klockan 2200Z på 04 Apr 2011IA. Analys av solfläcksgrupper och solaktivitet från 03-2100Z till 04-2100Z Solar activity was very low. New Region 1185 (N23E72)
was numbered today. Multiple CMEs were observed by Stereo Ahead
COR2 imagery. A long duration B-class event was associated with the
CME that lifted off of the Northeast limb at approximately 04/0509Z.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low to low with a slight chance for moderate activity (isolated
M-class event) from Region 1183 (N16W38) for the next three days (05
- 07 April).
IIA. Sammanfattning av geofysisk aktivitet 03-2100Z till 04-2100Z
The geomagnetic field was at quiet to unsettled levels. ACE solar
wind data showed wind speeds decreasing from approximately 600 km/s
to approximately 460/km/s as the coronal hole high speed stream (CH
HSS) effects wane. The greater than 2 MeV electron flux at
geosynchronous orbit was at high levels throughout the period.
IIB. Prognos för geofysisk aktivitet
Geomagnetic field activity is
expected to be mostly quiet on days one and two (05 - 06 April).
Activity is expected to increase to quiet to unsettled levels with
isolated active periods on day three (07 April) in response to
coronal hole effects. The CME mentioned above is not expected to be
geo-effective.
