Solar Activity

.24 hr Summary...
Solar activity remained at very low levels. No notable flares occurred
during the period. New Region 2359 (S14W02, Bxo/beta) was numbered
today, out ahead of Region 2358 (S03E58, Hax/alpha). Both Regions were
unremarkable otherwise. A type II radio sweep was observed 01/1333 UTC
with an estimated velocity of 1026 km/s. This activity was associated
with a CME observed in LASCO leaving the Sun around the NE limb as a
far-side event. No Earth-directed CMEs were noted in SOHO/LASCO
coronagraph imagery.

01/0848 UTC
Solar activity is expected to be very low with a chance for isolated
C-flares for the forecast period (02-04 Jun).

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 (02-04 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 continued at near nominal levels. Solar wind
were predominately steady between 335 km/s and 375 km/s. Total magnetic
field strength increased slightly from near 5 nT to around 8 nT with the
enhancement in solar wind, suggestive of a weak transient feature. The
Bz component fluctuated between north and south deviations prior to
31/2200 UTC before deflecting to a more sustained and frequent negative
orientation afterwards that peaked at about -6 nT. The phi angle
remained oriented in a positive (away) sector.

Solar wind parameters are expected to continue at or near nominal levels
for the forecast period (02-04 Jun).


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

The geomagnetic field is expected to remain at mostly quiet levels for
the forecast period (02-04 Jun). is the U.S. government's official web portal to all federal, state and local government web resources and services.
