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 017 publicerat klockan 2200Z på 17 Jan 2012IA. Analys av solfläcksgrupper och solaktivitet från 16-2100Z till 17-2100Z Solar activity reached moderate levels. Region 1401
(N18E38) produced an M1/1n at 17/0453Z. The other significant spot
group, Region 1402 (N28E40), was quiet during the period. Both
regions continued their growth phase in area and magnetic complexity
and are both classified E-type Beta-Gamma groups. New Region 1406
(S23W55) emerged on the disk as a D-type group.
IB. Prognos för solaktivitet
Solar activity is expected to be at
predominately low levels with a chance for M-class activity for the
next three days (18 - 20 January).
IIA. Sammanfattning av geofysisk aktivitet 16-2100Z till 17-2100Z
The geomagnetic field was at quiet to unsettled levels. Solar wind
velocities, as measured at the ACE satellite, steadily decayed
during the past 24 hours from a high of near 500 km/s to a low of
about 400 km/s at the end of the period. The Bz component of the
interplanetary magnetic field did not vary much beyond +/- 4 nT.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at mostly quiet levels through day one and most of
day two (18 - 19 January). By late on day two and through day three
(20 January), the field is expected to increase to quiet to
unsettled conditions, with isolated active periods. This activity
is due to the anticipated effects from a glancing blow as a result
of the 16 January CME.
