Solar Wind (24 hr Summary)
Solar wind parameters were indicative of a return to a slow solar wind regime. Solar wind speed averaged around 400 km/s and total field strength was between 1 to 8 nT, with only weak southward deviations of the Bz component. The phi angle was positive.
.

Forecast
A slow solar wind regime is expected to continue all three days (29-31 May).

.
Solar Activity (24 hr Summary)
Solar activity reached low levels. Region 2712 (N15E12, Csi/beta) was stable in growth, but managed a C2 flare at 28/1636Z, and several B-class flares. No CMEs were observed in available coronagraph imagery. 
.

Forecast
Solar activity is expected to remain very low, with a chance for C-class flares all three days (29-31 May) due primarily to the flare potential of Region 2712.
.
Energetic Particle (24 hr Summary)
The greater than 2 MeV electron flux was at normal levels and the greater than 10 MeV proton flux remained at background values.
.

Forecast
The greater than 2 MeV electron flux is expected to continue at normal to moderate levels and the greater than 10 MeV proton flux to remain at background levels all three days (29-31 May).
.
Geospace (24 hr Summary)
The geomagnetic field was quiet.
.

Forecast
The geomagn etic field is expected to be primarily quiet all three days (29-31 May).
