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 156 publicerat klockan 2200Z på 05 Jun 2010IA. Analys av solfläcksgrupper och solaktivitet från 04-2100Z till 05-2100Z Solar activity was very low. No flares were observed
during the past 24 hours. Region 1076 (S19W61) remains quiet and
stable. Newly numbered Region 1077 (N20W47) is an Axx Alpha spot.
IB. Prognos för solaktivitet
Solar activity is expected to remain
very low with only a slight chance for an isolated C-class flare.
IIA. Sammanfattning av geofysisk aktivitet 04-2100Z till 05-2100Z
The geomagnetic field was quiet over the past 24 hours. Solar winds
have decreased to near 450 km/s. The greater than 2 MeV electron
flux at geosynchronous orbit was at high levels during the past 24
hours.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to remain mostly quiet with isolated periods of unsettled
conditions on day 1 (6 June) due to elevated solar wind speeds and
brief periods of Bz south. Quiet to unsettled with intermittent
periods of active conditions are expected on days 2 and 3 (7-8
June). The increase in activity is due in part to weak coronal hole
effects expected on 7 June as well as the possible arrival of a slow
moving CME on 8 June. The CME is from a filament that disappeared on
3 June. A weak halo can be observed on LASCO C3 coronagraph images
from early 4 June as well as STEREO A and B coronagraphs from the
same period.
