Solar Activity
.24 hr Summary...
Solar activity was low. The majority of C-class X-ray activity
originated from the NE limb. Only minor changes were observed in the
spotted active regions on the Suns visible disk. No Earth-directed CMEs
were detected in available coronagraph imagery.
.Forecast...
Solar activity is expected to be at low levels, with a slight chance for
M-class (R1-R2/Minor-Moderate) flares through 11 Mar.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux reached high levels with a peak
flux of 2,160 pfu observed at 08/1730 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
09-11 Mar. The greater than 10 MeV proton flux is expected to continue
at background levels through 11 Mar.
Solar Wind
.24 hr Summary...
The solar wind environment was enhanced under continued negative
polarity CH HSS influences. Total magnetic field strength reached 9 nT,
and the Bz component was observed as far south as -8 nT. Solar wind
speeds were between ~450-550 km/s for most of the reporting period. The
phi angle was predominantly negative.
.Forecast...
Enhanced solar wind conditions are expected to persist through 10 Mar
due primarily to ongoing negative polarity CH HSS influences. Transient
influences are possible on 10 Mar as a CME from 06 Mar passes in close
proximity.
Geospace
.24 hr Summary...
The geomagnetic field reached active levels this period in response to
negative polarity CH HSS influences.
.Forecast...
The geomagnetic field is expected to reach active levels on 09 Mar, and
quiet to unsettled levels on 10-11 Mar, due to ongoing negative polarity
CH HSS influences. Additional enhancements are possible on 10 Mar as a
CME that left the Sun on 06 Mar passes in close proximity.
