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 159 publicerat klockan 2200Z på 08 Jun 2011IA. Analys av solfläcksgrupper och solaktivitet från 07-2100Z till 08-2100Z Solar activity decreased to very low levels. Region
1226 (S20W81) produced an isolated B-class flare. Region 1226
continued to gradually decay as it approached the west limb and was
classified as a 1-spot Axx type. The remaining numbered regions were
inactive. No new regions were numbered.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low through the period (09 - 11 June).
IIA. Sammanfattning av geofysisk aktivitet 07-2100Z till 08-2100Z
Geomagnetic activity was at quiet to minor storm levels. Unsettled to
minor storm levels occurred during 07/2100 - 08/0600Z, associated
with elevated solar wind speeds combined with increased IMF Bt and
periods of southward IMF Bz. Mostly quiet conditions occurred after
08/0600Z. The greater than 10 MeV proton event that began at
07/0820Z reached a maximum of 73 pfu at 07/1820Z and ended at
08/1710Z. The greater than 100 MeV event that began at 07/0735Z
reached a maximum of 4 pfu at 07/1025Z and ended at 08/0210Z.
IIB. Prognos för geofysisk aktivitet
Geomagnetic activity is
expected to be at quiet to active levels on day 1 (09 June) due to
the arrival of the halo coronal mass ejection (CME) observed on 07
June. Unsettled to active levels are expected on day 2 (10 June)
with a chance for minor to major storm levels as CME effects
persist. Activity is expected to decrease to quiet to unsettled
levels on day 3 (11 June) with a chance for active levels as CME
effects subside. There is a chance for a greater than 10 MeV proton
event at geosynchronous orbit on days 1 - 2 (09 - 10 June) due to
the arrival of the CME mentioned above.
