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 156 Issued at 2200Z on 05 Jun 2001IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z Solar activity was moderate. Two M-class events
occurred during the period. An M1/Sf from Region 9484 (S05W20) at
04/2259 UTC, and an M2/2n from Region 9488 (S20E33) at 05/0451 UTC.
Region 9488 also produced an C9/Sn at 05/1421 UTC. Several CME's
were noted by the LASCO instrument during the period, but none
appear earth-directed. Region 9489 (N17E52) was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be low
to moderate.
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic field was at quiet to unsettled conditions.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet to unsettled. Isolated active periods
are possible on the second and third day of the period due to a
favorably positioned coronal hole.
