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 214 publicerat klockan 2200Z på 02 Aug 2005

IA. Analys av solfläcksgrupper och solaktivitet från 01-2100Z till 02-2100Z

Solar activity remained at moderate levels today. Region 794 (S11E47) produced the largest flare of the period, an M4/1n event that occurred at 02/1831Z. There was an associated Tenflare and a Type II Radio sweep. An associated CME on the east solar limb was first seen in LASCO C2 imagery at 02/1854Z and may have a weak geoeffective component. This region also produced multiple B and C-class flares during the period and underwent growth in both magnetic complexity and sunspot count since yesterday. Region 792 (N12E12) produced a C6/Sn at 02/2016Z, prior to this event activity was limited to minor B-class events. The delta structure in the northern portion of the spot cluster and the total sunspot area have shown decay during the period. No new regions were numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to remain at moderate levels. Regions 792 and 794 have the potential of producing M-class flare activity.
IIA. Sammanfattning av geofysisk aktivitet 01-2100Z till 02-2100Z
The geomagnetic field was at quiet to unsettled levels.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected to be at quiet to unsettled levels on 03 August. The CME activity from yesterday and today could lead to isolated minor storming conditions on 04 August. Quiet to unsettled conditions should return by 05 August.
