Solar Activity

.24 hr Summary...
Solar activity remained very low. There were no sunspots on the visible
disk, and no Earth-directed CMEs were observed in available coronagraph
imagery.

.Forecast...
Solar activity is expected to remain very low on 24-26 May.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux was at normal to moderate levels,
and the greater than 10 MeV proton flux remained at background levels.

.Forecast...
The greater than 2 MeV electron flux is expected to be at normal to
moderate levels on 24-26 May. The greater than 10 MeV proton flux is
expected to continue at background levels.

Solar Wind

.24 hr Summary...
Solar wind parameters continued at background levels. Total field
strength was 7 nT or less. Bz briefly reached a deflection of -5 nT, but
was otherwise unremarkable. Solar wind speeds ranged from 330-370 km/s.
Phi angle was predominately in a negative orientation.

.Forecast...
Ambient background conditions are expected to continue over 24 May.
Minor enhancements in the solar wind are possible on 25 May as a result
of a weak, negative polarity CH HSS. Ambient conditions are expected to
return 26 May.

Geospace

.24 hr Summary...
The geomagnetic field was quiet.

.Forecast...
The geomagnetic field is expected to be at mostly quiet levels with
isolated unsettled conditions possible on 25 May with a weak, negative
polarity CH HSS.
