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 029 Välja antud 2200Z kuni 29 Jan 2012IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 28-2100Z kuni 29-2100Z Solar activity was at very low levels. Two new regions
emerged on the disk during the period: Region 1412 (S15W41) and
Region 1413 (N08E38). Both regions were magnetically simple Beta,
B-type groups. No new Earth-directed CMEs were observed.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at
very low levels with a chance for C-class activity for the next
three days (30 January - 01 February).
IIA. Summaarne geofüüsikaline aktiivsus 28-2100Z kuni 29-2100Z
The geomagnetic field was at quiet to unsettled levels. The period
began with ACE satellite wind velocities at about 450 km/s and
exhibited slow decay to end the period near 380 km/s. The Bz
component of the interplanetary magnetic field did not vary beyond
+/- 4 nT. The greater than 100 MeV proton event that began at
27/1900Z, reached a maximum of 11 pfu at 27/2140Z and ended at
28/2120Z. The greater than 10 MeV proton event that began at
27/1905Z and reached a maximum of 796 pfu at 28/0205Z was still in
progress at the time of this report, but flux levels had decayed to
below 100 pfu.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be at unsettled to active conditions with a chance for
isolated minor storm periods on day one (30 January). This increase
in activity is due to anticipated effects from the CME associated
with the 27 January X1 flare. Quiet to unsettled conditions with
isolated active periods are expected on day two (31 January) due to
residual CME effects. By day three (01 February), mostly quiet
conditions are expected. The greater than 10 MeV proton flux
levels, at geosynchronous orbit, are expected to decay to below
event threshold by 30/1800Z.
