Highlights of Solar and Geomagnetic Activity 01 - 07 April 2024
Solar activity reached moderate levels on 01 Apr due to an M3.9/Sf flare at 01/0132 UTC from Region 3625 (N13, L=174, class/area=Dai/80 on 01 Apr); the largest event of the period. The remainder of the period saw low-level solar activity with C-class flares observed from several unremarkable active regions. No Earth-directed CMEs were observed as a result of this period of activity. 

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 period. 

Geomagnetic field activity reached active levels on 01 Apr, and unsettled levels on 02-03 Apr, due to weak positive polarity CH HSS influences. Active conditions were observed again on 04 Apr, with unsettled levels observed on 05-06 Apr, due to weak negative polarity CH HSS influences. Quiet conditions and a nominal solar wind environment prevailed over 07 Apr. 

Forecast of Solar and Geomagnetic Activity 08 April - 04 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 continue at normal to moderate levels through 04 May. 

Geomagnetic field activity is expected to reach active levels on 09-10 Apr in response to anticipated positive polarity CH HSS influence. Quiet and quiet to unsettled conditions are expected to prevail throughout the remainder of the outlook period.
