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 203 Issued at 2200Z on 22 Jul 2005

IA. Analysis of Solar Active Regions and Activity from 21-2100Z to 22-2100Z

Solar activity was very low. No significant activity was observed during the period. No new regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 21-2100Z to 22-2100Z
The geomagnetic field was quiet to unsettled. Solar wind speed remains elevated at approximately 580 km/s. The greater than 2 MeV electrons at geosynchronous orbit reached high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on 23 July as the coronal hole high speed stream wanes. Predominantly quiet conditions are expected on 24 and 25 July.
