Solar Activity

.24 hr Summary...
Solar activity was very low and only low-level B-class flare activity
was observed.  Region 2615 (S07W07, Dai/beta) exhibited minor growth in
its intermediate and trailer spot areas while the remaining three active
regions were in decay.  No Earth-directed CMEs were observed in
available coronagraph imagery.

.Forecast...
Solar activity is expected to continue at very low levels, with a chance
for C-class and a slight for M-class flare activity, over the next three
days (04-06 Dec).

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux reached high levels this period
with peak flux of 6,640 pfu observed at 03/1550 UTC.  The greater than
10 MeV proton flux was steady at background levels throughout the
period.

.Forecast...
The greater than 2 MeV proton flux is expected to continue at high
levels over the next three days (04-06 Dec) and the greater than 10 MeV
proton flux is expected to persist at background levels throughout the
forecast period.

Solar Wind

.24 hr Summary...
Solar wind parameters reflected a background solar wind environment this
period.  Total field strength values were steady between 1-3 nT, Bz
values hovered around 0 nT, and solar wind speeds ranged between 295-320
km/s.  The phi angle was steady in a positive solar sector orientation
throughout the period.

.Forecast...
Solar wind parameters are expected to be slightly enhanced on days one
and two (04-05 Dec) due to the weak influence of a positive polarity CH
HSS.  Background solar wind conditions are expected on day three (06
Dec) with the return of a nominal solar wind regime.

Geospace

.24 hr Summary...
The geomagnetic field was quiet under a nominal solar wind regime.

.Forecast...
The geomagnetic field is expected to be quiet to unsettled on days one
and two (04-05 Dec) due to the influence of a positive polarity CH HSS.
Generally quiet conditions are expected on day three (06 Dec).
