Solar Activity

.24 hr Summary...
Solar activity was at low levels due to an isolated C1 flare at 01/2005
UTC from Region 2390 (S14W79, Cao/beta).  Slight growth and
consolidation was observed in the trailing spots of Region 2390.  Slight
decay was observed in Region 2393 (N17E22, Cao/beta).  The rest of the
spotted regions were stable.  No Earth-directed coronal mass ejections
were observed.

.Forecast...
Solar activity is expected to remain very low with a chance for C-class
activity for the next three days (02-04 Aug).

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux was at normal to moderate levels.
The greater than 10 MeV proton flux remained at background levels
through the period.

.Forecast...
The greater than 2 MeV electron flux is expected to be at moderate to
high levels for the forecast period (02-04 Aug). The greater than 10 MeV
proton flux is expected to remain at background levels (below
S1-Minor).

Solar Wind

.24 hr Summary...
Solar wind parameters continued to be under the influence of a negative
polarity coronal hole high speed stream (CH HSS).  Solar wind speeds
ranged from 520 km/s to 655 km/s.  Total field was between 2 nT and 7 nT
while the Bz component was variable between +/-6 nT.  Phi angle was
oriented in a negative (towards) sector.

.Forecast...
Solar wind parameters are expected to slowly decline towards background
levels by days two and three (03-04 Aug) as CH HSS effects diminish.

Geospace

.24 hr Summary...
The geomagnetic field was at quiet to unsettled levels.

.Forecast...
The geomagnetic field is expected to be at quiet to active levels on day
one (02 Aug) as CH HSS activity persists.  Quiet to unsettled levels are
expected on days two and three (03-04 Aug) as coronal hole effects
diminish.
