Activiteitenrapport
Bij elke genoemde zonnevlam in dit rapport werd een schaalfactor toegepast door het Space Weather Prediction Center (SWPC). Vanwege de SWPC-schaalfactor worden zonnevlammen 42% kleiner gerapporteerd dan voor de wetenschappelijke data. De schaalfactor werd verwijderd uit onze gearchiveerde zonnevlamdata om de werkelijke fysieke eenheden weer te geven.

IA. Analyse van de actieve zonneregio's en zonneactiviteit van 31-2100Z tot 01-2100Z
Solar activity was moderate during the past 24 hours.
All of today's flare activity was dominated by new Region 276
(S14E76), which produced an M1 at 0905 UTC, a C9/Sf at 1954 UTC, as
well as numerous additional C-class subflares. Observations of the
group so far indicate a relatively small (190 millionths) D-type
sunspot group. An erupting prominence was observed at 31/2200 UTC on
the Northwest limb and was associated with a type II sweep (shock
velocity 500 km/s) and a CME seen by LASCO. The remainder of the
regions on the disk were quiet and stable.
IB. Voorspelling zonneactiviteit
Solar activity is expected to be low
to moderate. Region 276 is expected to be the main driver of
activity, and has a fair chance for producing an additional M-class
event over the next three days.
IIA. Samenvatting geofysische activiteit 31-2100Z tot 01-2100Z
The geomagnetic field ranged from quiet to active levels during the
past 24 hours. Quiet conditions prevailed for most of the day, but
an increase to unsettled to active began at 1500 UTC. A marked
increase in solar wind velocity and total magnetic field strength
was observed beginning at 1300 UTC, but a predominantly positive
value for Bz suppressed activity until 1900 UTC, when Bz turned
weakly southwards. The interpretation of the enhanced solar wind
flow is not obvious, but seems most consistent with the passage of
transient flow due to the halo CME that occurred on 30 January. The
great than 2 MeV electron fluxes reached high levels during the past
24 hours.
IIB. Voorspelling geofysische activiteit
The geomagnetic field is
expected to be mostly active for the next 24 hours with a chance for
some isolated minor storm periods. Conditions should subside to
unsettled to active by day two, and return to mostly unsettled
levels by the third day.
