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 211 publicerat klockan 2200Z på 30 Jul 2002IA. Analys av solfläcksgrupper och solaktivitet från 29-2100Z till 30-2100Z Solar activity decreased to low levels. Regions 39
(S14W30), 44 (S20W33), and 50 (S08W19) produced isolated C-class
subflares. Region 39 began to gradually decay and simplify, but
retained a weakened delta magnetic configuration within its leader
spots as well as a delta in its trailer spots. Region 44 also began
to slowly decay, but retained a magnetic delta configuration within
its intermediate spots. Region 50 appeared to stabilize as a E-type
group of moderate size and complexity.
IB. Prognos för solaktivitet
Solar activity is expected to be
moderate. Isolated M-class flares are expected from Regions 39 and
44. Either region could produce a major flare during the period.
Region 50 could also produce an isolated M-class flare during the
period.
IIA. Sammanfattning av geofysisk aktivitet 29-2100Z till 30-2100Z
Geomagnetic field activity was at quiet to unsettled levels during
the period.
IIB. Prognos för geofysisk aktivitet
Geomagnetic field activity is
expected to be at unsettled levels on 31 July. Field activity is
expected to increase to unsettled to active levels during 01 - 02
August. There is a slight chance for a proton event during the
period.
