Rapport d'activité solaire
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.

IA. Analyse des régions solaires actives et activité du 21-2100Z au 22-2100Z
Solar activity was low. Just a single C-class flare
this period - a C1/Sf at 22/0949Z from Region 388 (S02W32). This
region has shown little change this period and still contains some
weak magnetic mixing. Moderately complex Region 386 (S06W08) still
maintains a weak delta configuration, but was quiet this period as
it continues to slowly decay. Region 387 (N18E10) is the largest
region the visible disk, but was also quiet. A new region rotating
around the east limb was numbered today as Region 390.
IB. Prévisions d'activité solaire
Solar activity is expected to continue
at low levels. There is a small chance for an isolated low M-class
flare from Regions 386, 387 and 388.
IIA. Résumé de l'activité géophysique du 21-2100Z au 22-2100Z
The geomagnetic field was unsettled to active due to a high speed
coronal hole stream. The greater than 2 MeV electron flux at
geosynchronous orbit reached high levels today.
IIB. Prévision de l'activité géophysique
The geomagnetic field is
expected to continue at unsettled to active levels due to coronal
hole high speed flow.

Comments
K-Indices
On 16 June, it was determined that a scaling problem exists with the Boulder magnetometer instrument. While this problem, and its fix are being investigated, the primary instrument for Boulder K-indices has been switched to the Boulder USGS (via Domsat) magnetometer, effective 1500 UTC on 16 June.
GOES Protons
To ensure continued operational monitoring of important energetic particle data, it is necessary to reassign primary/secondary designations for the GOES Space Environment Monitor (SEM) detectors. GOES 11 (113W) is now the primary satellite for protons. GOES 12 will continue as the primary satellite for magnetometer, X-ray, and electron measurements. GOES 10 (135W) will be the secondary satellite for all SEM sensors - magnetometer, X-ray, and energetic particles. Because of the degraded state of the proton data on GOES-10, its designation as the secondary source for proton data is a short-term solution. More permanent solutions have been identified and are being evaluated. Users will be notified when we define and schedule a permanent fix. Further details can be found at http://www.sec.noaa.gov/GOES.html.
