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 127 publicerat klockan 2200Z på 07 May 2011IA. Analys av solfläcksgrupper och solaktivitet från 06-2100Z till 07-2100Z Solar activity has been very low. Region 1203 (N17W41)
and Region 1204 (N17W27) are the only remaining active spotted
regions. All other regions have decayed to spotless plage.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low to low during days one through three (08-10 May).
IIA. Sammanfattning av geofysisk aktivitet 06-2100Z till 07-2100Z
The geomagnetic field was predominately quiet with isolate unsettled
conditions late in the period. The greater than 2 MeV electron flux
at geosynchronous orbit was at high levels throughout the period.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet to unsettled on days one and two (08-09 May).
Day three is expected to be quiet to unsettled for most of the day,
with a chance for an isolated active period late in the day. The
increase in activity is forecast due to a coronal hole high speed
stream (CH-HSS) becoming geo-effective. The co-rotating interactive
region associated with this CH-HSS is expected to arrive between
10/1800Z-11/0600Z and maintains the possibility of causing isolated
minor storm conditions especially at high latitudes.
