Sonnenaktivität
24h Zusammenfassung
Solar activity reached moderate levels. Region 3654 (S07W29,
Ehc/beta-gamma-delta) produced two R1 (Minor) events this period, the
largest of which was an M3.0 flare at 27/2140 UTC. Region 3654 exhibited
moderate development in the intermediate and trailer spots, and
developed a delta magnetic configuration. The remaining regions were
either stable or in decay. No Earth-directed CMEs were detected in
available imagery.
Vorhersage
Solar activity is expected to be at low levels over 28-30 Apr with a
chance for M-class flare (R1-R2/Minor-Moderate) activity.
Energiereiche Teilchen
24h Zusammenfassung
The greater than 2 MeV electron flux was at normal to moderate levels
and the greater than 10 MeV proton flux was steady at background levels.
Vorhersage
The greater than 2 MeV electron flux is expected to be at normal to
moderate levels over 28-30 Apr. The greater than 10 MeV proton flux is
expected to persist at background levels over 28-30 Apr.
Sonnenwind
24h Zusammenfassung
The solar wind environment was enhanced early in the period due to
positive polarity CH HSS influences. Total field strength reached a peak
of 13 nT and the Bz component was varied between +11/-10 nT. Solar wind
speeds were steady near 400 km/s. The phi angle was in a mostly positive
orientation through the period.
Vorhersage
Enhanced solar wind conditions are likely over 28-30 Apr due to CH HSS
influences and possible transient activity associated with multiple CMEs
that are expected to pass in close proximity to Earth over the next few
days.
Geospace
24h Zusammenfassung
The geomagnetic field was at quiet to active levels this period.
Vorhersage
Geomagnetic field activity is expected to range from quiet to active
levels on 28 Apr, and quiet to unsettled levels on 29-30 Apr, due to the
anticipated influence of CH HSSs combined with potential transient
influence of multiple near-miss CMEs from the past several days. A
chance for G1 (Minor) storm periods exists on 28 Apr should these
features arrive at Earth and carry periods of significant southward Bz.
