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 147 publicerat klockan 2200Z på 27 May 2002

IA. Analys av solfläcksgrupper och solaktivitet från 26-2100Z till 27-2100Z

Solar activity increased to moderate levels. Region 9957 (N10W73) produced an M2/2f flare at 27/1810 UTC associated with minor discrete radio emission. Gradual decay may have continued in this region, but it was difficult to tell given limb foreshortening effects. However, it appeared that a weak delta persisted within its northern cluster of spots. Region 9961 (S22W30) produced isolated subflares as it continued to decay. Region 9970 (N05E41) appeared to stabilize as a simply-structured D-type spot group. Active surging and subflare activity was observed on the southeast limb near SE17. This limb activity may indicate the active return of old Region 9934 (S16, L = 211). A filament erupted from the northeast quadrant around midday. The eruption was associated with C2 X-ray event and a CME off the northeast limb. The CME did not appear to be Earth directed.
IB. Prognos för solaktivitet
Solar activity is expected to be low to moderate. There is a fair chance for an isolated M-class flare during the period. There is a slight chance for a major flare as well.
IIA. Sammanfattning av geofysisk aktivitet 26-2100Z till 27-2100Z
Geomagnetic field activity increased to quiet to active levels with minor storm conditions observed at some high latitude stations. This activity was likely due to coronal hole effects. ACE solar wind data indicated a gradual rise in velocities during the period with peak velocities in the 700 to 800 km/sec range.
IIB. Prognos för geofysisk aktivitet
Quiet to active conditions are expected during the first half of the period. Quiet to unsettled conditions are expected during the remainder of the period. There is a slight chance for a proton event until 29 May.
