Solar Activity

.24 hr Summary...
Solar activity was very low. A new, but so far benign, active region
was numbered as NOAA active region number 2773 (Bxo/beta N28E62). No
Earth-directed CMEs were observed.

.Forecast...
Solar activity is expected to be very low on 24-26 Sep.

Energetic Particles

.24 hr Summary...
The greater than 2 MeV electron flux reached moderate levels while the
greater than 10 MeV proton flux continued at background values.

.Forecast...
The greater than 2 MeV electron flux is expected to reach moderate
levels while the greater than 10 MeV proton flux is expected to persist
at background levels on 24-26 Sep.

Solar Wind

.24 hr Summary...
Solar wind parameters reflected slightly elevated CH HSS conditions.
Total magnetic field strength was mostly 4 to 6 nT before increasing to
near 8nT. The Bz component generally varied between +3 to -5 nT. Solar
wind speeds increased from near 350 km/s to 465 km/s. Phi angle was
predominately in a positive orientation.

.Forecast...
The solar wind environment is expected to persist under a recurrent,
positive polarity CH HSS on days one through three (24-26 Sep).

Geospace

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

.Forecast...
The geomagnetic field is expected to be unsettled to active on days one
through three (24-26 Sep) due to the arrival of the aforementioned CH
HSS.
