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 21 publicerat klockan 2200Z på 21 Jan 2013IA. Analys av solfläcksgrupper och solaktivitet från 20-2100Z till 21-2100Z Solar activity has been at very low levels for the past 24
hours. There are currently 3 numbered sunspot regions on the disk.
Region 1658 (S12W46) produced the largest flare of the period, a B4
flare, at 21/0930Z. Region 1654 (N09W88) produced two B3 flares while
Region 1660 (N12W15) was fairly quiet, yet was the most magnetically
complex region on the disk. It has continued to show growth in the
trailer spots and extended its length from five degrees to just over
seven. This region currently appears to be a Dai/Beta-Gamma region and
will be the area of interest for the next few days.
IB. Prognos för solaktivitet
Solar activity is expected to be at low
levels on days one, two, and three (22 Jan, 23 Jan, 24 Jan).
IIA. Sammanfattning av geofysisk aktivitet 20-2100Z till 21-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 409 km/s at
21/0029Z. Total IMF reached 16.2 nT at 21/1513Z. The maximum southward
component of Bz reached -5.2 nT at 21/1513Z. Electrons greater than 2
MeV at geosynchronous orbit reached a peak level of 268 pfu.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected
to be at quiet levels for the next three days (22 Jan, 23 Jan, 24 Jan).
