Highlights of Solar and Geomagnetic Activity 08 - 14 April 2024
Solar activity reached high levels on 11 Apr due to an M5.4 flare at 11/1706 UTC from Region 3637 (S12, L=231, class/area=Cso/40 on 14 Apr); the largest event of the period. Moderate levels of solar activity were observed on 13-14 Apr due to an M2.4 flare at 13/0502 UTC and an M4.3 flare at 14/0232 UTC from Region 3637. The remainder of the period saw low levels of solar activity with C-class flares observed. Two CMEs, associated with filament eruptions near N20E02 at 11/0600 UTC and S16W14 at 12/0020 UTC, were anticipated to arrive on 14 Apr, but ultimately were not detected in the solar wind by the end of 14 Apr.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels throughout the week.
Geomagnetic field activity was quiet to unsettled over 08-10 Apr due to positive polarity CH HSS influences. Quiet and unsettled levels were observed over 11-12 Apr, and quiet levels were observed over 13-14 Apr, as CH HSS influences subsided and nominal solar wind conditions returned.
Forecast of Solar and Geomagnetic Activity 15 April - 11 May 2024
Solar activity is expected to be at low to moderate levels throughout the outlook period, with C-class flare activity expected and a varying chance for M-class flare activity.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels throughout the period.
Geomagnetic field activity is likely to reach G1 (Minor) storm levels on 15 Apr due to CH HSS influences and CME effects. Quiet and quiet to unsettled levels are expected to prevail throughout the remainder of the period.
