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 060 publicerat klockan 2200Z på 01 Mar 2005IA. Analys av solfläcksgrupper och solaktivitet från 28-2100Z till 01-2100Z Solar activity continues at very low levels. There is
only one single, small sunspot on the visible disk. A series of
complex eruptions were observed on LASCO imagery beginning at
28/2330Z. These were likely backsided events, as there is no
apparent frontside source for this CME activity.
IB. Prognos för solaktivitet
Solar activity is expected to continue
at very low levels.
IIA. Sammanfattning av geofysisk aktivitet 28-2100Z till 01-2100Z
The geomagnetic field was quiet to unsettled with isolated active
periods at high latitudes. A high speed coronal hole stream
continues to buffet the geomagnetic field. Solar wind speed ranged
from 600 - 700 km/s, but the IMF Bz was predominantly northward.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to continue at quiet to unsettled levels with isolated
active periods through 03 March. Quiet levels are expected on 04
March as the high speed solar wind stream rotates out of a
geoeffective position.
