Solar Activity
.24 hr Summary...
Solar activity was at low levels. C-class flare activity occurred from
Regions 4381 (N09W69, Cso/beta), 4387 (N09E40, Cro/beta), and 4389
(N13E60, Ero/beta). The largest was a C4.6 at 10/1845 UTC from
Region 4381. Regions 4384 (N09W44, Hsx/beta) and 4381 continued to
slowly decay. Slight growth was observed in Region 4388 (S15W33,
Cri/beta). The rest of the spot groups were relatively stable. No
Earth-directed CMEs were observed.
.Forecast...
Solar activity is expected to be at low levels, with a slight chance for
M-class (R1-R2/Minor-Moderate) flares through 14 Mar.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux reached high levels with a peak
flux of 1,730 pfu observed at 10/1735 UTC. The greater than 10 MeV
proton flux was at background levels.
.Forecast...
The greater than 2 MeV electron flux is expected to reach high levels on
10-12 Mar. The greater than 10 MeV proton flux is expected to continue
at background levels through 14 Mar.
Solar Wind
.24 hr Summary...
Solar wind parameters were mildly enhanced, possibly due to transient
influence. Total field increased after 10/1030 UTC to near 9 nT while
the Bz ranged from +6/-8 nT. Solar wind speed ranged from 389-500 km/s.
Phi angle was mostly negative.
.Forecast...
Slightly enhanced solar wind parameters are likely to continue through
11 Mar. Nominal levels are expected to return on 12 Mar before
enhancements are again expected 13-14 Mar due to the onset of
a positive polarity coronal hole high speed stream.
Geospace
.24 hr Summary...
The geomagnetic field was quiet to active levels.
.Forecast...
The geomagnetic field is expected to be at quiet to active levels on 11
Mar as slightly enhanced solar wind conditions persist. Mostly quiet
conditions are expected on 12 Mar. Active levels are expected 13-14 Mar
with possible isolated periods of G1 (Minor) storming due to the onset
of positive polarity coronal hole high speed stream.
