Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 096 Issued at 2200Z on 05 Apr 2008
IA. Analysis of Solar Active Regions and Activity from 04/2100Z
to 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. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 04/2100Z to 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. Geophysical Activity Forecast: 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.
