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 067 publicerat klockan 2200Z på 08 Mar 2003IA. Analys av solfläcksgrupper och solaktivitet från 07-2100Z till 08-2100Z Solar activity increased to low levels today. The
largest flare during the period was a C2.6/Sf event that occurred in
Region 206 (N05E63) at 08/0957Z. White light currently shows this
group to consist of a single large penumbral spot which may share
both polarities. Will be able to better analyze once region rotates
further onto disk. A C1.0 flare was observed from Region 301
(N22W18) at 08/0116Z. There was little in the way of magnetic
structure changes seen in this region during the period. Region 297
(S14W25) produced a couple low level B-class flares today. Regions
307 (S26W02) and 308 (n08E75) were newly assigned today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low levels. There is a small chance for an isolated M-class flare
from Region 296 (N13W31).
IIA. Sammanfattning av geofysisk aktivitet 07-2100Z till 08-2100Z
The geomagnetic field has been at quiet to unsettled levels. There
was an isolated active period at mid latitudes in response to a
southward oscillation in the Bz component of the interplanetary
magnetic field between 08/1500 and 1800Z. The coronal hole high
speed stream that has been geoeffective for the past several days
appears to have rotated out of its favorable position early in the
period. The greater than 2 MeV electron fluxes at geosynchronous
orbit reached high levels again today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to continue at quiet to unsettled levels throughout the
period.
