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 299 publicerat klockan 2200Z på 26 Oct 2011

IA. Analys av solfläcksgrupper och solaktivitet från 25-2100Z till 26-2100Z

Solar activity was at low levels due to a single C1 x-ray event at 26/1001Z from Region 1324 (N12W38). Associated with this event was a partial-halo CME, first observed in LASCO C2 imagery lifting off the NW limb at 26/1000Z. GOES-15 SXI imagery first observed material movement from Region 1324 in a W-NW direction at about 26/0800Z. Limited imagery prevented a thorough analysis of the CMEs potential geoeffectiveness. The region exhibited significant decay in area and spot count and was classified as a beta magnetic configuration. Regions 1325 (N17W12) and 1327 (S20W67) also indicated decay in both area coverage and spot count. The remaining regions were unchanged.
IB. Prognos för solaktivitet
Solar activity is expected to be low with a slight chance for M-class activity all three days (27 - 29 October).
IIA. Sammanfattning av geofysisk aktivitet 25-2100Z till 26-2100Z
The geomagnetic field was quiet at all latitudes. Solar wind speeds decayed through the period from near 550 km/s to about 400 km/s while the Bz component of the interplanetary magnetic field did not vary much beyond +/- 4 nT.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected to be quiet on day one (27 October). Quiet to unsettled conditions are expected on days two and three (28 - 29 October) as a recurrent coronal hole high speed stream rotates into a geoeffective position.
