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 131 publicerat klockan 2200Z på 11 May 2005IA. Analys av solfläcksgrupper och solaktivitet från 10-2100Z till 11-2100Z Solar activity has been moderate. For 11 May, Region
758 (S10W55) generated an M1.2 at 0641Z, an M1.1/1F at 1938Z, and a
series of C-class events over the last 24 hours. This region
continues to maintain strong magnetic intensity, and has a good
potential for further activity. Regions 764 (S10E01) and 763
(S14E70) were newly numbered today, and Region 762 (S11E04) was
reclassified as two regions (Regions 762 and 764).
IB. Prognos för solaktivitet
Solar activity is expected to be
moderate for the next three days. Regions 758 and 759 (N12E33)
continue to harbor a good potential for M-class activity with a
slight chance for a major or proton producing flare.
IIA. Sammanfattning av geofysisk aktivitet 10-2100Z till 11-2100Z
The geomagnetic field has been at quiet to unsettled levels. The
greater than 2 MeV electron flux at geosynchronous orbits reached
high levels today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet to unsettled for the next three days.
