|
| Solar activity remained very low. There were no sunspots on the visible
disk, and no Earth-directed CMEs were observed in available coronagraph
imagery. |
| Solar activity is expected to remain very low on 24-26 May. |
|
|
| 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. |
| 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 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. |
| 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. |
|
|
| The geomagnetic field was quiet. |
| 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. |
