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 182 Issued at 2200Z on 01 Jul 2010IA. Analysis of Solar Active Regions and Activity from 30-2100Z to 01-2100Z Solar activity was very low during the past 24 hours.
IB. Solar Activity Forecast
Solar activity is expected to be very
low throughout the forecast period (02-04 July).
IIA. Geophysical Activity Summary 30-2100Z to 01-2100Z
The geomagnetic field was mostly unsettled with an isolated active
period from 03-06Z. 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 quiet to unsettled with a chance for isolated active
periods at high latitudes on days 1 and 2 (02-03 July) due to a
recurrent coronal hole high speed stream. Mostly quiet conditions
are expected on day 3 (04 July) as the effects from the coronal hole
high speed stream subside.
