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 109 publicerat klockan 2200Z på 19 Apr 2010IA. Analys av solfläcksgrupper och solaktivitet från 18-2100Z till 19-2100Z Solar activity was very low. No flares were observed
during the last 24 hours. The visible disk remained spotless. A
CME was noted on SOHO and STEREO imagery on the southwest limb at
approximately 18/2300Z. The source of this activity is unknown,
however, it may be related to a prominence located just behind the
southwest limb. In addition, a second CME was observed at 19/1754Z
on the SOHO C2 image. This activity is likely associated with a
filament that lifted off the NW limb (approx. N40W85).
IB. Prognos för solaktivitet
Solar activity is expected to remain
very low for the next three days (20-22 April).
IIA. Sammanfattning av geofysisk aktivitet 18-2100Z till 19-2100Z
The geomagnetic field was quiet during the last 24 hours.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to remain quiet for day one (20 April). Quiet to unsettled
levels with isolated active periods are expected for days two and
three (21-22 April). Activity is expected due to possible effects
from a weak CME observed on 15 April and two coronal hole high speed
streams rotating into a geoeffective position.
