Solar Activity
.24 hr Summary...
Solar activity continued at low levels this period. Region 4432 (N13W36,
Dai/beta-gamma) continued to show signs of development, adding several
intermediate and leader spots, and picking up a gamma configuration.
This region produced most of the flare activity, including a C4.2 flare
at 08/1551 UTC; the strongest of the period. A new area of flux
emergence, with possible spots embedded, was noted rotating onto the NE
limb near N19E89. Foreshortening prohibited proper identification and
analysis, but this area will be monitored as it rotates onto the visible
disk. The remaining regions were mostly unremarkable. No Earth-directed
CMEs were detected in available coronagraph imagery.
.Forecast...
Solar activity is expected to be at predominately low levels over 09-11
May, with a chance for M-class (R1-R2/Minor-Moderate) flares and a
slight chance for an X-class (R3-Strong or greater) flare.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux was at normal to moderate levels.
The greater than 10 MeV electron flux was at background levels.
.Forecast...
The greater than 2 MeV electron flux is likely to reach high levels on
09-11 May. The greater than 10 MeV proton flux is expected to persist at
background levels through 11 May.
Solar Wind
.24 hr Summary...
The solar wind environment remained slightly enhanced under persistent,
yet weakening, positive polarity CH HSS influences. Total magnetic field
strength averaged near 4 nT, the Bz component was predominately neutral
or northward throughout the period, and solar wind speeds averaged at a
slightly elevated 500-550 km/s. Phi oscillated between a positive and
negative orientation throughout the period.
.Forecast...
Solar wind parameters are expected to remain mildly enhanced through 11
May under positive polarity CH HSS influences.
Geospace
.24 hr Summary...
The geomagnetic field was quiet and unsettled.
.Forecast...
The geomagnetic field is expected to be at quiet to unsettled levels on
09-11 May as positive polarity CH HSS influences persist.
