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 015 publicerat klockan 2200Z på 15 Jan 2002IA. Analys av solfläcksgrupper och solaktivitet från 14-2100Z till 15-2100Z Solar activity has been moderate. Region 9775 (S06W69)
was most active, producing an M1/Sf event at 14/2246 UTC, and
several other subfaint C-class flares during the period. This
region is exhibiting some growth in magnetic complexity and areal
coverage as it approaches the west limb. Other sources of weak
C-class flare activity during the period included Regions 9782
(N06E20) and 9773 (N16W80).
IB. Prognos för solaktivitet
Solar activity is expected to be low
to moderate.
IIA. Sammanfattning av geofysisk aktivitet 14-2100Z till 15-2100Z
The geomagnetic field has been quiet. Particle fluxes for both >2MeV
electrons and >10MeV protons reached event levels during the period.
>2MeV electrons briefly exceeded 1000 pfu at geosynchronous orbit
near local noon, as measured on GOES-8, during 15/1405-1615 UTC. A
proton event for >10MeV flux reached event threshold of 10 pfu at
15/1435 UTC, and remains in progress with a current flux of about 12
pfu. The slow enhancement in proton flux is likely from the west
limb CME event of 14 January, with the delay in enhancement due to
the intervening effects of a coronal hole high speed stream.
IIB. Prognos för geofysisk aktivitet
Geomagnetic field activity is
expected to be mainly quiet with some isolated unsettled periods.
The >10MeV proton event is expected to end during the first day of
the period.
