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 174 publicerat klockan 2200Z på 23 Jun 2011IA. Analys av solfläcksgrupper och solaktivitet från 22-2100Z till 23-2100Z Solar activity was very low. There were three B class
flares in the past 24 hours. Region 1240 (S18E02) produced a B2 at
0213Z and appeared to be slowly growing. Region 1236 (N16W46) was
unchanged but produced a B5 at 1240Z and a B4 at 1407Z. Region 1239
(N16W27) was slowly decaying.
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 22-2100Z till 23-2100Z
The geomagnetic field has been unsettled to active for the past 24
hours. ACE solar wind data showed elevated velocities around 600 to
700 km/s consistent with a high speed stream from a favorably
positioned coronal hole. A sudden impulse was observed at 0258Z and
measured 22 nT at the Boulder magnetometer. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels during the
period.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be active with a chance for minor storm periods at
mid-latitudes and isolated major storm periods at high latitudes for
tomorrow (24 June). This activity is expected as a response to the
arrival of the halo CME observed on 21 June. Conditions are
expected to decrease to unsettled to active levels for the second
day (25 June), and quiet to unsettled levels for the third day (26
June).
