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 076 publicerat klockan 2200Z på 17 Mar 2010IA. Analys av solfläcksgrupper och solaktivitet från 16-2100Z till 17-2100Z Solar activity has been at very low levels for the past
24 hours. Region 1054 (N15W37) was in a gradual decay phase with
decreased spot count and area. Region 1056 (N17E46) was numbered
today and is magnetically classified as a Beta.
IB. Prognos för solaktivitet
Solar activity is expected to be at
very low levels with a slight chance for C-class flares for the next
three days (18-20 March).
IIA. Sammanfattning av geofysisk aktivitet 16-2100Z till 17-2100Z
The geomagnetic field was quiet to unsettled at mid latitudes for the
past 24 hours. There was an isolated active period at high latitudes
between 0300Z - 0600Z. Solar wind observations from the ACE
spacecraft showed elevated velocities around 520 km/s and densities
around (1-3 p/cc). These signatures are consistent with a coronal
hole high-speed stream, presumably from the northward extension of
the southern polar coronal hole.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at quiet to unsettled levels for day one (18 March)
due to the arrival of a partial-halo CME observed on 13 March.
Activity is expected to decrease to mostly quiet levels on days two
and three (19-20 March).
