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 020 Välja antud 2200Z kuni 20 Jan 2012IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 19-2100Z kuni 20-2100Z Solar activity was very low with no flares detected.
Region 1401 (N15W01) showed intermediate spot development during the
period and was classified as an Eki group with beta magnetic
structure. Region 1402 (N28E03) showed no significant changes and
was classified as a Dki group with beta magnetic structure. No new
regions were numbered.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
through the period (21 - 23 January) with a chance for an M-class
flare from Region 1401 or 1402.
IIA. Summaarne geofüüsikaline aktiivsus 19-2100Z kuni 20-2100Z
The geomagnetic field was quiet. An enhancement of the greater than
10 MeV proton flux at geosynchronous orbit began around 20/0800Z and
continued through the end of the period. The enhancement was
associated with the long-duration M3/2n flare observed on 19
January.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be at quiet levels during day 1 (21 January) and most of
day 2 (22 January). Field activity is expected to increase to
unsettled to active levels late on day 2 and day 3 (23 January) with
a chance for minor storm levels due to the arrival of the halo-CME
observed on 19 January. There will be a slight chance for a greater
than 10 MeV proton event at geosynchronous orbit during the period.
