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 128 publié à 2200Z le 08 May 2010IA. Analyse des régions solaires actives et activité du 07-2100Z au 08-2100Z Solar activity remained at low levels. Region 1069
(N41W78) produced isolated C-class flares as it approached the west
limb. The largest of these was a C9/1f at 08/0459Z associated with
radio bursts at 245 MHz and 410 MHz. New Region 1071 (S20W42), a
small A-type spot, was numbered. No Earth-directed CMEs were
observed during the period.
IB. Prévisions d'activité solaire
Solar activity is expected to be low
on day 1 (09 May) with a chance for isolated C-class flares from
Region 1069. Activity is expected to decrease to very low levels
during days 2 - 3 (10 - 11 May) due to the departure of Region 1069
early on 10 May.
IIA. Résumé de l'activité géophysique du 07-2100Z au 08-2100Z
Geomagnetic field activity was at mostly quiet levels. ACE solar wind
measurements indicated Earth remained within a gradually subsiding
coronal hole high-speed stream. Solar wind velocities decreased from
518 to 437 km/sec during the period. The greater than 2 MeV electron
flux at geosynchronous orbit reached high levels during the period.
IIB. Prévision de l'activité géophysique
Geomagnetic field activity is
expected to be at quiet to unsettled levels during days 1 - 2 (09 -
10 May) with a slight chance for active levels. Field activity is
expected to increase to unsettled levels on day 3 (11 May) with a
chance for active levels due a recurrent co-rotating interaction
region/coronal-hole high-speed stream.
