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 2010IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z Solar activity was very low during the last 24 hours.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low throughout the forecast period (01-03 July).
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
The geomagnetic field was mostly unsettled to active with an isolated
minor storm at high latitudes observed from 00-03Z. The greater
than 2 MeV electron flux at geosynchronous orbit was at high levels
during the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly unsettled with isolated active periods for day
1 (01 July) due to a recurrent coronal hole high speed stream.
Quiet to unsettled levels with isolated active periods are expected
for days 2 and 3 (02-03 July) as the effects from the coronal hole
high speed stream subside.
