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 153 publicerat klockan 2200Z på 02 Jun 2011IA. Analys av solfläcksgrupper och solaktivitet från 01-2100Z till 02-2100Z Solar activity was low. Region 1226 (S22E01) produced
several C-class events during the period. This region is a Dsi
group with a beta magnetic classification. A further analysis of
LASCO imagery correlated the C4/1f at 01/1708Z from Region 1226 to a
Earth directed partial-halo CME. This event was observed by STEREO
COR2 imagery at 01/2009Z. Region 1227 (S19E13) is also a D-type
group with a beta magnetic classification. It produced a C3/2n at
02/0746Z with an associated Type IV radio sweep, and a Earth
directed partial-halo CME. STEREO COR2 and LASCO C3 imagery
observed the event with a plane-of-sky speed of 831 km/s. New
Region 1232 (N10E61) was numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be low
with a slight chance for an M-class event.
IIA. Sammanfattning av geofysisk aktivitet 01-2100Z till 02-2100Z
The geomagnetic field was quiet to unsettled. 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 quiet to unsettled for day one (03 June). Active
conditions with isolated minor storm levels are expected for day two
(04 June) as a coronal hole high-speed stream becomes geoeffective,
and additional effects from recent CME activity. Day three (05
June) is expected to be at quiet to unsettled levels, with isolated
active conditions.
