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 163 Issued at 2200Z on 12 Jun 2001IA. Analysis of Solar Active Regions and Activity from 11-2100Z to 12-2100Z Solar activity was low. The largest event of the period
was a C6/1n flare and faint CME from Region 9488 (S18W56). Small
centimetric bursts, a Type II radio sweep (687 km/s), and a small
>10 MeV proton enhancement accompanied this flare. Minor C-class
flares were also observed in Regions 9487 (N22W55), 9492 (N21W15),
and 9494 (S07W80). New Region 9502 (S25E68) was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be low
to moderate. An isolated M-class flare is possible.
IIA. Geophysical Activity Summary 11-2100Z to 12-2100Z
The geomagnetic field was at mostly low levels. A single period of
unsettled conditions were observed between 12/1800 - 2100Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to continue at quiet to unsettled levels.
