Solar Activity
.24 hr Summary...
Solar activity decreased to very low levels. New Region 4416 (N19E20,
Bxo/beta) was numbered. The two remaining active regions with spots were
stable and quiet over the past 24 hours. No Earth-directed CMEs were
observed in available coronagraph imagery.
.Forecast...
Solar activity is expected to reach low levels on 10-12 Apr.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux was at high levels with a peak flux
of 10,679 pfu at 09/1605 UTC. The greater than 10 MeV proton flux was at
background levels.
.Forecast...
The greater than 2 MeV electron flux is expected to be at normal to
moderate levels over 10-12 Apr. The greater than 10 MeV proton flux is
expected to remain at background levels.
Solar Wind
.24 hr Summary...
Solar wind parameters became enhanced this period following the onset of
CIR effects preceding +CH HSS influences. Total magnetic field strength
reached a peak of 14 nT, and the Bz component was observed as far south
as -8 nT. Solar wind speeds gradually increased from 350 km/s to a peak
of around 500 km/s.
.Forecast...
Solar wind parameters are expected to remain enhanced over 10-12 Apr due
to CIR effects followed by +CH HSS influences.
Geospace
.24 hr Summary...
The geomagnetic field reached active levels following the onset of CIR
effects.
.Forecast...
Periods of G1 (Minor) storm levels are likely on 10-11 Apr due to CIR
effects followed by +CH HSS influences. Periods of active conditions are
likely on 12 Apr as +CH HSS influences wane.
