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 230 publicerat klockan 2200Z på 18 Aug 2006IA. Analys av solfläcksgrupper och solaktivitet från 17-2100Z till 18-2100Z Solar activity was very low during the past 24 hours.
Region 904 (S13W42) produced a couple of B-class flares today. This
region continues to be large, but has lost some of its magnetic
complexity in the trailing spots.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low to low, with just a slight chance for an isolated M-class flare
from Region 904.
IIA. Sammanfattning av geofysisk aktivitet 17-2100Z till 18-2100Z
The geomagnetic field was quiet to active during the past 24 hours.
An active period was observed between 18/0300Z - 18/0600Z. A weak
shock was observed by ACE at approximately 18/1550Z. Following the
shock, the solar wind speed at ACE increased from approximately 360
km/sec to about 420 km/sec. However, the IMF remained predominantly
northward. There was a 5 nT sudden impulse observed at the Boulder
magnetometer at 18/1644Z.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at active to minor storm levels, with possible
isolated major storm conditions on 19 August, due to the full halo
CME observed on 16 August. Unsettled to active levels are expected
on 20 August, due to a coronal hole moving into a geoeffective
position. Quiet to unsettled conditions should return on 21 August.
