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 22-2100Z au 23-2100Z
Solar activity was at moderate levels. While being
void of spots for the past several days, Region 9997 (S17W72)
managed to produced an M1/2f flare at 23/0255 UTC. A few minor
discrete radio bursts accompanied the flare. Region 5 (N13W13)
produced a C1/1n flare at 23/0824 UTC and a B7/Sf flare at 23/1822
UTC. No appreciable changes seen in this region today. Region 8
(S09E13) remains the largest region on the disk but has continued to
show quiescent characteristics. New Regions 12 (N19E20), 13
(N04E07), and 14 (S18E50) were assigned today.
IB. Prévisions d'activité solaire
Solar activity is expected to be at
low levels.
IIA. Résumé de l'activité géophysique du 22-2100Z au 23-2100Z
The geomagnetic field activity was at quiet to predominantly
unsettled conditions. The Bz component of the IMF remained
southward throughout most of the day.
IIB. Prévision de l'activité géophysique
The geomagnetic field is
expected to be at quiet to unsettled levels throughout the period.

This message is for users of the NOAA/SEC Space
Weather Operations sunspot region numbers. As you
may have noticed, region number 10000 was assigned
on June 14. Space Weather operations is going
through the sequence of Region numbers as 9998,
9999, 0000, 0001, and so on. SEC's product text
discussions of the active regions will ignore the
leading zeroes (for example, we will say 'Region
number 5' rather than Region number '0005'). However,
the Geoalert product, the Region Report product, as
well as the USAF and IUWDS data exchange codes will
preserve the 4 digit format. The necessity of using
four digits is for operational purposes only. For
historical purposes all regions beyond Region 9999
will be understood to be in a series of region numbers
10000 and higher.
