Informe actividad solar
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.

Informe conjunto USAF/NOAA de actividad Solar y Geofísica
SDF Número 096 Publicado el 2200Z a las 05 Apr 2008IA. Análisis de regiones solares activas y de actividad desde 04-2100Z hasta 05-2100Z Solar activity was very low. Spotless plage Region 989
(S11W67) produced an isolated low-level B-class flare. SOHO/LASCO
images showed a halo CME, first visible in C2 at 05/1626Z. The CME
appeared to be from the back side, based on STEREO Ahead EUVI 195
images and the GOES- 10 X-ray signature. No new active regions were
numbered.
IB. Pronóstico de la actividad solar
Solar activity is expected to be very
low.
IIA. Resumen de la actividad geofísica 04-2100Z a 05-2100Z
Geomagnetic field activity ranged from quiet to major storm levels
with a Kp = 6 observed during 05/1500 - 1800Z. ACE measurements
indicated Earth entered a fast solar wind flow from a recurrent
low-latitude coronal hole in the southern hemisphere. Solar wind
velocities increased during the period with a peak of 671 km/sec
detected at 05/1634Z. IMF Bz reached a minimum of -7 nT at 05/1441Z.
The greater than 2 MeV electron flux at geosynchronous orbit briefly
reached high levels during the period.
IIB. Pronóstico de la actividad geofísica
Geomagnetic field activity is
expected to be at unsettled to minor storm levels on day 1 (06
April) with major storm levels possible at high latitudes. Activity
is expected to decrease to unsettled to active levels during days 2
- 3 (07 - 08 April) as coronal hole effects persist.
