Solar Activity

.24 hr Summary...
Solar activity was at very low levels.  New Region 2357 (N09E45,
Bxo/beta) was numbered today.  Both Regions 2356 (S15E47, Hsx/alpha) and
2357 were relatively stable and unproductive.  Minor material movement
was observed in the large filament structure in the NW quadrant, however
the filament remains intact as of this report.

Solar activity is expected to be at very low levels with an increasing
chance for C-class activity over the next three days (30 May-01 Jun) due
to the return of old region 2339 (N13, L=129) on or about 30 May.

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 levels this

The greater than 2 MeV electron flux is expected to be at normal levels
for the forecast period (30 May-01 Jun).  The greater than 10 MeV proton
flux is expected to remain at background levels throughout the forecast

Solar Wind

.24 hr Summary...
Solar wind parameters were slightly enhanced above background levels
over the period.  Solar wind speeds increased from approximately 360
km/s to near 450 km/s.  Total field decreased from 9 nT to 6 nT while
the Bz component fluctuated between +8 nT and -7 nT.  Phi angle was
oriented in a positive (away) sector.

Solar wind parameters are expected to continue at or near nominal levels
for the forecast period (30 May-01 Jun).


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

The geomagnetic field is expected to be at quiet to unsettled levels on
day one (30 May).  Mostly quiet conditions are expected on days two and
three (31 May-01 Jun). is the U.S. government's official web portal to all federal, state and local government web resources and services.
