Solar activity report

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.

Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 280 Issued at 2200Z on 06 Oct 2000

IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z

Solar activity was low. Today's largest event was a C2 x-ray event at 1011Z which was not observed optically. All of the regions on the disk were quiet and stable. An 8 degree filament near S40E06 disappeared sometime during the past 24 hours. The event is spatially correlated with a CME that entered the LASCO/C2 field of view at 1006Z.
IB. Solar Activity Forecast
Solar activity is expected to be low for the next three days.
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
The geomagnetic field ranged from quiet to active during the past 24 hours. Yesterday's disturbance persisted through 05/2400Z but conditions became quiet after 06/0000Z with the northward turning of the interplanetary magnetic field. Today's solar wind was characterized by declining speeds, low densities, and weak, northwardly directed magnetic fields, all of which lead to predominantly quiet conditions.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be mostly quiet for the next two days, and is expected to become unsettled by the third day.
