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 026 Välja antud 2200Z kuni 26 Jan 2004IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 25-2100Z kuni 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. Päikese aktiivsuse ennustus
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. Summaarne geofüüsikaline aktiivsus 25-2100Z kuni 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. Geofüüsikalise aktiivsuse ennustus
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).
