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.

Rapport de l'USAF/NOAA sur l'activité solaire et géophysique
SDF numéro 183 publié à 2200Z le 02 Jul 2005IA. Analyse des régions solaires actives et activité du 01-2100Z au 02-2100Z Solar activity was low. The majority of today's
activity came from Region 785 (S22W06), which produced five C-class
events. The largest of these was a C3/Sf at 0316 UTC. Region 785 has
shown steady growth during the past 24 hours. An additional C-flare
(C1 at 1614 UTC) was produced by Region 786 (N10E62). Region 783
(S06E21) is currently the largest group on the disk with an area of
570 millionths, but was stable and quiet. New Region 788 (S07E71)
rotated into view today and is a simple H-type spot.
IB. Prévisions d'activité solaire
Solar activity is expected to be
mostly low, but there is a chance for an isolated M-class during the
next three days (3-5 July). Of the eight spotted regions on the
disk, 785 and 783 appear to be the most likely sources for future
M-class level activity.
IIA. Résumé de l'activité géophysique du 01-2100Z au 02-2100Z
The geomagnetic field began the period at active levels due to the
effects of a high speed stream from a coronal hole. However, the
interplanetary magnetic field weakened significantly at about 0700
UTC, and conditions have been quiet to unsettled since then. Solar
wind velocities remain elevated but were declining during the past
24 hours, with typical values of 540-560 km/s by forecast issue
time.
IIB. Prévision de l'activité géophysique
The geomagnetic field is
expected to be predominantly unsettled, but there is a continued
chance for occasional active periods during the next two days (03-04
July) as effects from the coronal hole are expected to linger.
Conditions should decline to mostly quiet by the third day (05
July).
