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.

SDF Number 185 Issued at 2200Z on 04 Jul 2001

IA. Analysis of Solar Active Regions and Activity from 03-2100Z to 04-2100Z

Solar activity was very low. Only one optically uncorrelated B-class x-ray flare occurred during the period. All regions on the visible disk remain small and magnetically simple.
IB. Solar Activity Forecast
Solar activity is expected to be very low to low.
IIA. Geophysical Activity Summary 03-2100Z to 04-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be quiet to unsettled for the next three days.
