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 241 publicerat klockan 2200Z på 29 Aug 2002

IA. Analys av solfläcksgrupper och solaktivitet från 28-2100Z till 29-2100Z

Solar activity was at moderate levels. After further review of a more comprehensive database set, it appears that the M4 flare that occurred yesterday (no region has been assigned to flare) at 28/1859 UTC could have originated from several different source regions. The most probable source region appears to be from the northeast limb which corresponds to Region 95 (N07E76), which rotated onto the visible disk and became a newly numbered region today. Region 95 did produce the largest flare today, an impulsive M3/Sf flare occurring at 29/1252 UTC with an associated 720 pfu Tenflare. Proximity to limb hinders any meaningful analysis of this region at this time as the most recent white-light images indicate the trailing cluster of spots have yet fully rotated into view. Three other optically uncorrelated low level M-class flares occurred today along with multiple C-class flares. Region 87 (S08W20) showed steady decay over the period although it retains a weak delta magnetic structure in the southeast portion of the spot complex. Despite the region's magnetic structure it only managed to produce minor activity today. The remaining active regions were of little note. Regions 93 (S16E13) and 94 (S17E67) were also assigned today.
