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 222 publicerat klockan 2200Z på 10 Aug 2001IA. Analys av solfläcksgrupper och solaktivitet från 09-2100Z till 10-2100Z Solar activity was low. Region 9562 (N05W82) produced
a C8/Sf event at 10/0136 UTC with an associated Type II radio sweep.
A new region was numbered today as Region 9575 (S03E04). The LASCO
images from yesterday observed a partial halo coronal mass ejection.
The possible cause was a North-South filament channel eruption
observed on EIT images at 10/0936 UTC close to central meridian.
IB. Prognos för solaktivitet
Solar activity is expected to be low
to moderate. Isolated M-class events are possible from several
regions on the disk.
IIA. Sammanfattning av geofysisk aktivitet 09-2100Z till 10-2100Z
The geomagnetic field was quiet to unsettled. A greater than 10 MeV
proton event began at 10/1020 UTC with a peak flux observed at
10/1635 UTC of 17 pfu. Protons remain enhanced at this time. The
actual source of the event is not currently known as several
possibilities exists.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet to unsettled on 11 August. Disturbed
conditions are expected on 12th and 13th of August due to a high
speed coronal hole flow with minor to major storm conditions
possible as a result of the CME on 09 August. The greater than 10
MeV protons should remain enhanced through the period with a chance
of exceeding threshold on 12 August due to the CME passage.
