Solar Activity

.24 hr Summary...
Solar activity was at low levels due to weak C-class flare activity from
Regions 4401 (N25W20, Eai/beta), 4404 (N14E39, Hsx/alpha) and 4405
(S27E52, Eao/beta-gamma). New Region 4408 (N09E72, Hsx/alpha) was
numbered this period. No significant changes were noticed in the spotted
regions.

No Earth-directed CMEs were observed in available coronagraph imagery.

.Forecast...
Solar activity is expected to be low with a high chance (50%) for
M-class flares (R1-R2/Minor-Moderate radio blackouts) through 31 Mar.

Energetic Particle

.24 hr Summary...
Electrons greater than 2 MeV at geosynchronous orbit reached a peak
level of 1,600 pfu at 28/1900 UTC. The greater than 10 MeV proton flux
remained at background levels.

.Forecast...
The greater than 2 MeV electron flux is expected to continue to reach
high levels through 29 Mar before returning to normal to moderate levels
on 30-31 Mar. The greater than 10 MeV proton flux is expected to
continue at background levels.

Solar Wind

.24 hr Summary...
Solar wind parameters reflected a mostly nominal regime until
approximately 28/2020 UTC when a weak enhancement in the IMF began.
Total field increased to 7 nT and the Bz component underwent a southward
deflection reaching -7 nT. Solar wind speeds were primarily under 400
km/s. Phi was predominantly in a negative solar sector, but became
variable post enhancement.

.Forecast...
Enhancements from recurrent, positive polarity CH HSS influences are
anticipated to begin by late 29 Mar and persist through 30 Mar.

Geospace

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

.Forecast...
Quiet to active levels are expected on 29 Mar. G1 (Minor) geomagnetic
storming is likely on 30 Mar due to recurrent positive polarity CH HSS
effects. Unsettled to active conditions are then expected to persist
into 31 Mar.
