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 162 Issued at 2200Z on 11 Jun 2001IA. Analysis of Solar Active Regions and Activity from 10-2100Z to 11-2100Z Solar activity was low. The largest events of the
period were the successive C5 and C7 x-ray bursts at 11/0451Z and
11/0552Z respectively. These events appeared to be associated with
activity on the SE limb near new Region 9501 (S14E69), and a
filament eruption south of Region 9488 (S19W45). CME's were observed
with both events, but did not appear earthbound. Region 9494
(S08W69) was responsible for some minor C-class activity, but though
maintaining moderate complexity and size, flare output has decreased
considerably. Three new regions were numbered today - Regions 9499
(N18E17), 9500 (N10E71), and 9501, making a total of 15 spot groups
on the visible disk..
IB. Solar Activity Forecast
Solar activity is expected to be low
to moderate. A small chance for an M-class flare exist in several
regions, primarily in Region 9494.
IIA. Geophysical Activity Summary 10-2100Z to 11-2100Z
The geomagnetic field was quiet to unsettled. The greater than 2 MeV
electrons were at moderate levels for the latter half of the period.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to continue at quiet to unsettled levels.
