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 2009IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z Solar activity was very low. No flares were detected.
The visible disk was spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
Geomagnetic field activity was at mostly quiet levels. ACE solar wind
observations indicated velocities gradually decreased from 551
km/sec to 449 km/sec during the period. IMF Bz varied from +4 to -4
nT during the period.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to be at quiet to unsettled levels during days 1 - 2 (01 -
02 July). Field activity is expected to decrease to quiet levels on
day 3 (03 July).
