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 187 Issued at 2200Z on 06 Jul 2009IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z Solar activity was low. Region 1024 (S27W26) produced
an isolated C1/Sf flare at 06/1705Z. Region 1024 showed minor decay
with loss of some intermediate spots, but retained a mix of
polarities near region center.
IB. Solar Activity Forecast
Solar activity is expected to be very
low with a chance for an isolated C-class flare.
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
Geomagnetic field activity was at quiet levels.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to be at quiet levels during days 1 - 2 (07 - 08 July).
Activity is expected to increase to quiet to unsettled levels on day
3 (09 July) due to an increase in solar wind velocities associated
with a favorably positioned coronal hole.
