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 026 publicerat klockan 2200Z på 26 Jan 2004IA. Analys av solfläcksgrupper och solaktivitet från 25-2100Z till 26-2100Z Solar activity was low due to two C-class events during
the past 24 hours. The first was a C6 at 25/2241 UTC which had the
greatest contribution from a flare in Region 543 (S17W89), although
Region 542 (N06W82) flared at the same time and also contributed to
the total flux. The second was a C1 at 0610 UTC from Region 542. All
three of the currently spotted regions on the disk (542, 543, and
544 at N03W76) will be rotating around the west limb in the next 24
hours. A CME was observed by LASCO off the southeast limb, but the
absence of disk activity strongly suggests a backside source for the
event.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low to low. There may be a gradual rise in background levels over
the next three days with the return of old Region 536 (latitude S11)
on 28 January.
IIA. Sammanfattning av geofysisk aktivitet 25-2100Z till 26-2100Z
The geomagnetic field ranged from quiet to active levels. The greater
than 2 MeV electron fluxes were at high levels during the past 24
hours.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be mostly unsettled for the next 24 hours (27 January).
An increase to unsettled to active is expected on the 28th due to
possible effects from a favorably positioned, positive polarity
coronal hole. Conditions should return to mostly unsettled by the
third day (29 January).
