Solar Activity
.24 hr Summary...
Solar activity was at low levels. Region 2038 (S09W88) produced a C2
x-ray flare at 26/1459 UTC. New Region 2047 (S19E56) was numbered. The
spotted regions on the disk either exhibited little change or slight
decay. No Earth-directed CMEs were detected.
.Forecast...
Solar activity is expected to be at low levels for the next three days
(27-29 Apr) with a slight chance for M-class flares (NOAA Scale R1/R2 -
Minor/Moderate) on 27 April.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels. The greater than 10 MeV proton flux at geosynchronous orbit
was at background levels.
.Forecast...
The greater than 2 MeV electron flux at geosynchronous orbit is expected
to be at moderate to high levels for day one (27 Apr) and normal to
moderate levels for days two and three (28-29 Apr). The greater than 10
MeV proton flux at geosynchronous orbit is expected to remain at
background levels for the forecast period.
Solar Wind
.24 hr Summary...
Solar wind conditions, measured at the ACE spacecraft, were nominal for
the past 24 hours. Solar wind speed was steady around 375 km/s, IMF Bt
was near 3 nT while the Bz component varied between -1 to -3 nT. The Phi
component indicated a mostly negative (toward) orientation throughout
the period.
.Forecast...
Solar wind conditions are expected to continue to be nominal for the
next three days (27-29 Apr).
Geospace
.24 hr Summary...
The geomagnetic field was at quiet to unsettled levels.
.Forecast...
Mostly quiet conditions are forecast for the next three days (27-29
Apr).
