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 161 Issued at 2200Z on 10 Jun 2002

IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z

Solar activity was at low levels. Two optically uncorrelated C1 x-ray flares comprised the flare activity for the period. Region 9987 (S15W29) grew in magnetic complexity and penumbral coverage today. Even so, several point brightenings and intermittent dark surging were all that kept this region from being quiescent during the past 24 hours. Region 9985 (N18W51) showed a continued decay in spot count and magnetic complexity. Most other active regions on the visible disk remain little changed. New Region 9995 (N10W01) was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be at low levels. Region 9987 has the potential to produce an isolated M-class flare.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field activity was at quiet to active levels. A coronal hole may have been responsible for the active conditions that began near mid-period.
IIB. Geophysical Activity Forecast
The geomagnetic field activity is expected to be at quiet to unsettled levels throughout the forecast period.
