Solar Activity
.24 hr Summary...
Solar activity was at low levels. The largest flare was a C3.6 at
03/0708 UTC from Region 4424 (N17W78, Dao/beta). Minor decay was
observed in Regions 4428 (S24W51, Dai/beta), 4429 (S04W07, Dai/beta),
and 4431 (S16E24, Dso/beta), while the remining regions were stable. No
Earth-directed CMEs were detected in available coronagraph imagery.
.Forecast...
Solar activity is expected to be at low levels with a chance for
M-flares (R1-R2/Minor-Moderate) on 04-06 May.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux was at normal to moderate levels.
The greater than 10 MeV proton flux was at background levels.
.Forecast...
The greater than 2 MeV electron flux is expected to be at normal to
moderate levels on 04-06 May. The greater than 10 MeV proton flux is
expected to remain at background levels through 06 May.
Solar Wind
.24 hr Summary...
Solar wind parameters were consistent with waning negative polarity CH
HSS influences. Total field strength reached a peak of 6 nT, and the Bz
component briefly reached -6 nT. Solar wind speeds ranged between
~400-450 km/s throughout the period.
.Forecast...
The solar wind environment is expected to remain weakly enhanced over
04-06 May as negative polarity CH HSS influences slowly diminish.
Geospace
.24 hr Summary...
The geomagnetic field was at quiet to unsettled levels in response .#TIDE.VA.USA.NOAM
