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 191 Issued at 2200Z on 10 Jul 2001IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity was at very low levels. Region 9531
(S06W08) produced a B4/Sf flare at 10/0710 UTC. The only other
flare of note was an optically uncorrelated B7 at 10/1225 UTC. Two
newly numbered regions rotated into view on the east limb today:
9534 (N18E68) and 9535 (N11E76). Both appear simply structured and
remained quiescent today, as did the other numbered regions on the
visible disk.
IB. Solar Activity Forecast
Solar activity is expected to be at
very low to low levels.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field was at quiet to unsettled levels throughout the
period.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to remain at predominantly quiet to unsettled levels for
the next three days.
