Päikese aktiivsuse aruanne
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.

Ühine USAF / NOAA päikese- ja geofüüsikaalase aktiivsuse aruanne
SDF number 152 Välja antud 2200Z kuni 01 Jun 2011IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 31-2100Z kuni 01-2100Z Solar activity was low. Region 1226 (S22E14) produced
three C-class events, the largest was a C4/1f at 01/1708Z. This
region is a Csi type group with a beta magnetic classification and
has decayed in both sunspot count and white light aerial coverage.
Region 1227 (S19E26) has also shown signs of decay in white light
areal coverage, but retains its D-type group and beta-gamma magnetic
classification. Region 1228 (N17E31) produced a C2/Sf at 01/0253Z.
Region 1231 (N09E68) was numbered early in the period. The STEREO
COR2 imagery observed a CME around 01/0609Z and another around
06/2009Z. Further analysis will be performed as LASCO imagery
updates to determine if these will be Earth directed.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
with a slight chance for an M-class event.
IIA. Summaarne geofüüsikaline aktiivsus 31-2100Z kuni 01-2100Z
The geomagnetic field was quiet to active. An increase in activity
was observed on the Boulder magnetometer around 01/0800Z. This
activity may have been due to the CME observed on 29 May. There
were no observations available from the ACE spacecraft from
01/0028Z to 01/0771Z. The greater than 2 MeV electron flux at
geosynchronous orbit was at high levels throughout the period.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be at quiet to unsettled conditions with isolated active
levels for the next three days (02-04 June). Activity is expected
due to continued coronal hole high speed stream effects.
