| Solar activity remained very low. There were no sunspots on the visible
disk and no Earth-directed CMEs observed in available coronagraph
imagery. |
| Solar activity is expected to remain very low 06-08 May. |
|
|
| The greater than 2 MeV electron flux was normal to moderate and the
greater than 10 MeV proton flux continued at background values. |
| The greater than 2 MeV electron flux is expected to be normal to
moderate 06-08 May and the greater than 10 MeV proton flux is expected
to remain at background. |
|
|
| Solar wind parameters were indicative of a slow regime. Total IMF
strength was mainly 2 to 4 nT and the Bz component was mostly weak
northward directed. Solar wind speed decreased from ~425 km/s to end of
period values of 325-340 km/s. The phi angle was primarily positive,
with a few brief occasions of negative orientation. |
| A slow solar wind regime is anticipated to continue 06-08 May. |
|
|
| The geomagnetic field was quiet. |
| The geomagnetic field is expected to remain quiet 06-08 May. |
