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 173 publicerat klockan 2200Z på 22 Jun 2011 :::::::::: CORRECTED COPY ::::::::::IA. Analys av solfläcksgrupper och solaktivitet från 21-2100Z till 22-2100Z Solar activity was very low. There was only one flare
during the past 24 hours, a B2 at 0458Z from Region 1239 (N18W14).
Region 1236 (N16W32) is the largest region on the disk but has
decayed somewhat and is now a 140 millionths, C-type sunspot group.
Region 1239 and 1240 (S19E16) are both small, B-type sunspot groups.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low with a chance for an isolated C-class flare.
IIA. Sammanfattning av geofysisk aktivitet 21-2100Z till 22-2100Z
The geomagnetic field was quiet to unsettled during the past 24
hours. Observations of the solar wind from the ACE spacecraft
indicate a noticeable increase in solar wind velocity during the
last three hours of the analysis interval with end-of-period speeds
at about 600 km/s. The signatures appear to be consistent with a
high speed stream from a favorably positioned coronal hole.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be mostly active with a chance for minor storm periods
at mid-latitudes and major storm periods at high latitudes for the
next two days (23-24 June). Effects from the high speed stream
should prevail early on the 23rd. An additional contribution to
activity is expected sometime between 1200-1800Z on the 23rd due to
the arrival of the halo CME observed on 21 June. Conditions should
decrease to unsettled to active levels for the third day (25 June).
