Solaktivitetsrapport

Ethvert nævnt soludbrud i denne rapport har en skaleringsfaktor anvendt af Space Weather Prediction Center (SWPC). På grund af SWPC-skaleringsfaktoren rapporteres soludbrud som 42 % mindre end for videnskabelige kvalitetsdata. Skaleringsfaktoren er blevet fjernet fra vores arkiverede soludbrudsdata for at afspejle de sande fysiske enheder.

Fælles USAF/NOAA-rapport om sol- og geofysisk aktivitet

SDF nummer 222 Udstedt til 2200Z på 10 Aug 2011

IA. Analyse af solaktive områder og aktivitet fra 09-2100Z til 10-2100Z

Solar activity was low. Region 1263 (N17W93) produced a C6 x-ray flare at 10/1044Z, the largest flare of the past 24 hours. The magnetic complexity and area of Region 1263 decreased since yesterday and it ended the period as an Ekc type spot group with beta-gamma characteristics. A Type II (659 km/s) radio emission occurred at 10/1607Z and was coincident with material movement and darkening on STEREO-B EUVI imagery in the northeast quadrant of the solar disk.
IB. Solaktivitetsprognose
Solar activity is expected to be low with a chance for moderate activity as Region 1263 rotates around the west limb.
IIA. Geofysisk aktivitetsoversigt 09-2100Z til 10-2100Z
The geomagnetic field was predominantly quiet with one period of active levels at mid latitudes. The solar wind speed at the ACE spacecraft was near 550 km/s. The Bz component of the interplanetary magnetic field remained within +/- 4 nT of zero. A discontinuity in density and Phi angle was observed between 10/06Z and 07Z, when Phi became positive then rotated back to negative over the next 8 hours. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the period.
IIB. Geofysisk aktivitetsprognose
The geomagnetic field is expected to be quiet to unsettled on Day 1 (11 Aug) with a slight chance for active conditions, particularly at high latitudes. The remaining two days (12-13 Aug) are expected to be predominantly quiet. Detailed analysis of the CME associated with the X6 flare on 09/0805Z suggests the bulk of the material will not be geoeffective. A slight disruption in the geomagnetic field may be observed with shock passage.
