Solar Activity

.24 hr Summary...
Solar activity was at low levels.

Solar activity was at low levels. Region 4105 ()S14W38, Eai/beta-gamma)
produced the largest flare of the period, a C8.7/1n at 05/1547 UTC. A
region of emerging flux was observed in the SE quadrant and will be
assigned an active region number if it persists. The remaining numbered
regions on the visible disk were in gradual decay. No Earth-directed
CMEs were observed in available coronagraph imagery.

.Forecast...
Solar activity is expected to be low with a chance for M-class flares
(R1-R2/Minor-Moderate) on 06-08 Jun.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux reached moderate to high levels.
The greater than 10 MeV proton flux was near background levels.

.Forecast...
The greater than 2 MeV electron flux is expected to continue at moderate
to high levels through 08 Jun. The greater than 10 MeV proton flux is
expected to continue at or near background levels.

Solar Wind

.24 hr Summary...
Solar wind parameters were trended towards nominal levels. Total
magnetic field strength was at or below 5 nT. No significant periods of
southward Bz were observed. Solar wind speeds were in steady decline,
ending the period near 450 km/s. Phi angle transitioned from variable to
mostly negative after 05/2230 UTC.

.Forecast...
Influence from a HSS is likely to persist through 08 Jun. Additional
modest enhancements from a slow, glancing-blow CME that left the Sun on
03 Jun are possible around mid-to-late 07 Jun.

Geospace

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

.Forecast...
The geomagnetic field is expected to be quiet to unsettled on 06-07 Jun
as HSS activity continues. G1 (Minor) storm levels are likely with the
anticipated onset of CME that left the Sun on 03 Jun around mid-to-late
on 07 Jun. On 08 Jun, unsettled to active levels are expected.
