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 002 publicerat klockan 2200Z på 02 Jan 2002IA. Analys av solfläcksgrupper och solaktivitet från 01-2100Z till 02-2100Z Solar activity was at moderate levels. Region 9754
(S07W68) generated the largest flare of the day, producing an M2/1n
flare at 02/1252 UTC. This region grew in magnetic complexity
during the period and exhibits a much tighter spot cluster than was
seen yesterday in white light. Regions 9764 (N14W50) and 9751
(N04W89) also contributed to today's activity producing small
C-class flares. Region 9767 (S23E36) has been relatively quiescent
through the period producing a lone optical Sf flare. A decrease in
area was seen in spot coverage during the period, although magnetic
structure remained unchanged in Region 9767. New Regions 9769
(S19W33), 9770 (N08W29), and 9771 (S20E17) were numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
moderate levels.
IIA. Sammanfattning av geofysisk aktivitet 01-2100Z till 02-2100Z
The geomagnetic field has been at quiet to unsettled levels. The
greater than 10 MeV proton event that began at 30/0245 UTC reached a
maximum flux of 108 pfu at 31/1620 UTC. This event has been on a
very slow decrease since max and is at 33 pfu at the time of this
writing.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to remain at quiet to unsettled levels. The greater than
10 MeV proton event is expected to end late on day two of the
forecast.
