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 072 publicerat klockan 2200Z på 13 Mar 2011IA. Analys av solfläcksgrupper och solaktivitet från 12-2100Z till 13-2100Z Solar activity was low. Regions 1166 (N10W65) and 1169
(N20W34) have both produced C-class events. The daily consensus has
Region 1166 as decreased in both white light areal coverage and
sunspot count with a Ekc type spot group and a beta-gamma magnetic
classification. Region 1169 has maintained its area and spot count
and is a simple beta magnetic classification with a Cro type spot
group.
IB. Prognos för solaktivitet
Solar activity is expected to be low
with a chance for an M-class event.
IIA. Sammanfattning av geofysisk aktivitet 12-2100Z till 13-2100Z
The geomagnetic field was quiet to unsettled. The ACE spacecraft
observed solar wind speeds during the past 24 hours averaging around
550 km/s with the interplanetary magnetic field Bz fluctuating
between -4/+5 nT. Observations suggest that the earth is still
under the influence of the coronal hole high speed stream. The
greater than 2 MeV electron flux at geosynchronous orbit reached
high levels during the period.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet to unsettled with a chance for isolated active
levels for day one (14 March). Days two and three (15-16 March) are
expected to be predominately quiet as the effects from the coronal
hole high speed stream subside.
