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 126 publicerat klockan 2200Z på 06 May 2010IA. Analys av solfläcksgrupper och solaktivitet från 05-2100Z till 06-2100Z Solar activity decreased to very low levels. A single
low-level B-class flare occurred during the period. Region 1069
(N42W51) showed a decrease in area, but maintained a beta-gamma
magnetic configuration. An eruptive prominence and associated CME
(estimated velocity 507 km/sec) occurred near the southwest limb
very early in the period. The CME did not appear to be
Earth-directed.
IB. Prognos för solaktivitet
Solar activity is expected to be low
during days 1 - 2 (07 - 08 May) with a chance for an isolated
M-class flare from Region 1069. Activity is expected to decrease to
very low levels on day 3 (09 May) as Region 1069 crosses the west
limb.
IIA. Sammanfattning av geofysisk aktivitet 05-2100Z till 06-2100Z
Geomagnetic field activity was at quiet to unsettled levels. However,
a brief period of active levels was detected at Boulder around
06/0800Z. ACE solar wind measurements indicated Earth remained
within a coronal hole high-speed stream. Solar wind velocities
varied from 491 - 584 km/sec during the period. The greater than 2
MeV electron flux at geosynchronous orbit reached high levels during
the summary period.
IIB. Prognos för geofysisk aktivitet
Geomagnetic field activity is
expected to be at quiet to unsettled levels during days 1 - 3 (07 -
09 May). There is also a chance for active levels during days 2 - 3
(08 - 09 May) in response to recent CME activity.
