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 181 Issued at 2200Z on 30 Jun 2006

IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z

Solar activity continues at very low levels. Active Regions 897 (N07E02) and 898 (S06E40) produced minor B-class flares. Both regions are in decay.
IB. Solar Activity Forecast
Solar activity is expected to continue at very low levels. There is a slight chance for a C-class flare.
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
The geomagnetic field was quiet to unsettled. Solar wind speed is elevated due to a high speed coronal hole stream.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled on 01 and 02 July. Active to minor storm periods are expected on 03 July as a recurrent coronal hole high speed stream rotates into a geoeffective position.
