Solar Activity

.24 hr Summary...
Solar activity was at low levels. Region 4409 (N02W37, Eai/beta)
produced most of the C-flare activity this period, including a C2.8 at
05/2347 UTC; the strongest of the period. The region exhibited minor
development over the past 24 hours, but remained largely unchanged from
the previous reporting period. The remaining spotted regions on the
visible disk were either stable or in gradual decay. No Earth-directed
CMEs were observed in available coronagraph imagery.

.Forecast...
Solar activity is expected to be at low levels over 06-08 Apr, with a
chance for M-flares (R1-R2/Minor-Moderate) and a slight chance for an
X-flare (R3/Strong), driven primarily by the flare potential of Region
4409.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux reached high levels with a peak
flux of 6,000 pfu at 05/1645 UTC. The greater than 10 MeV proton flux
returned to background levels during the period.

.Forecast...
The greater than 2 MeV electron flux is expected to reach high levels
on 06-08 Apr. There is a slight chance for the greater than 10 MeV
proton flux to exceed S1 (Minor) solar radiation storm levels over 06-08
Apr.

Solar Wind

.24 hr Summary...
Solar wind parameters suggested waning influence from a negative
polarity CH HSS. Total magnetic field strength was steady between 4-6
nT, and no significant periods of southward Bz were observed. Wind
speeds were steady at around 550 km/s throughout the period. Phi angle
was predominantly oriented in the negative solar sector, with sporadic
oscillations into a positive orientation throughout the period.

.Forecast...
The solar wind environment is expected to remain mildly enhanced on 06
Apr, and possibly into early 07 Apr, as negative polarity CH HSS
influences subside. Mostly nominal conditions are expected to prevail
for the remainder of 07 Apr, through 08 Apr.

Geospace

.24 hr Summary...
The geomagnetic field was at quiet to unsettled levels under waning
negative polarity CH HSS influences.

.Forecast...
The geomagnetic field is expected to be at quiet to unsettled levels on
06-07 Apr, with mostly quiet levels expected on 08 Apr.
