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 069 Issued at 2200Z on 09 Mar 2008

IA. Analysis of Solar Active Regions and Activity from 08-2100Z to 09-2100Z

Solar activity was very low. The visible disk is spotless.
IB. Solar Activity Forecast
Solar activity is expected to continue at very low levels.
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
The geomagnetic field was at quiet to minor storm levels due to the influence of a recurrent coronal hole high speed stream. Solar wind at the ACE spacecraft increased from 438 km/s to a maximum of 691 km/s at 09/2023Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to range from quiet to active levels with isolated minor storm periods possible for the next three days (10 - 12 March), due to the coronal hole high speed stream. Isolated major storm conditions are possible at high latitudes during this period.
