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 151 publicerat klockan 2200Z på 31 May 2011IA. Analys av solfläcksgrupper och solaktivitet från 30-2100Z till 31-2100Z Solar activity has been low. Region 1226 (S22E27) and
Region 1227 (S18E39) each produced C1 x-ray events in the past 24
hours. Region 1226 was classified as a Dhc group with Beta magnetic
characteristics while Region 1227 was a Dsi group with more complex
Beta-Gamma characteristics. Region 1228 (N17E50) rapidly evolved
into a Cso type group as new trailing spots emerged. New Region
1230 (N19E58) was numbered today. This new region, and the remainng
regions, were generally quiescent, small and magnetically simple.
IB. Prognos för solaktivitet
Solar activity is expected to be low,
with a slight chance for M-class events for the next three days (1 -
3 Jun).
IIA. Sammanfattning av geofysisk aktivitet 30-2100Z till 31-2100Z
The geomagnetic field ranged from quiet to active levels over the
past 24 hours. Heliospheric imagery from STEREO-B suggests the
increased activity was the result of a transient, weak CME. 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 unsettled to active on day 1 (01 Jun) , quiet to
unsettled on day 2 (02 Jun), and unsettled to active on day 3 (03
Jun). ENLIL model output indicates the passage of the 29 May CME
early on day 1. A brief return to generally quiet conditions on day
2 is followed by disturbed conditions on day 3 as a recurrent
coronal hole high speed stream begins to influence the
magnetosphere.
