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 207 publicerat klockan 2200Z på 26 Jul 2002IA. Analys av solfläcksgrupper och solaktivitet från 25-2100Z till 26-2100Z Solar activity has been high. Region 44 (S21E17)
produced five M-class events. The largest was an M8/2n at 26/2112
UTC. It also produced an M4/1n at 26/0010 UTC with an associated
250 sfu Tenflare and a long duration M1/Sn at 26/0829 UTC. This
region has grown significantly and is currently 430 millionths of
white light with 42 spots and a magnetic beta-gamma configuration.
This region is located to the southwest of Region 39 (S16E22) which
has an area of 940 millionths of white light and a magnetic delta
configuration. Three new regions were numbered today as Regions 48
(N18E52), 49 (S06W30) and 50 (S07E36).
IB. Prognos för solaktivitet
Solar activity is expected to be low
to moderate. Isolated major flares are possible from Regions 39 and
44.
IIA. Sammanfattning av geofysisk aktivitet 25-2100Z till 26-2100Z
The geomagnetic field was quiet to active. The greater than 10 MeV
proton event that started 22/0655 UTC is still in progress with the
tentative maximum of 28 sfu at 23/1025 UTC.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet to unsettled. Isolated active conditions are
possible as a result of the activity from the past several days.
The greater than 10 MeV proton event is expected to drop below
threshold within the next 24 hours.
