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.
