Highlights of Solar and Geomagnetic Activity
27 May - 02 June 2024

Solar activity ranged from low to high levels throughout the period.
Region 3697 (S18, L=350, class/area=Eki/420 on 30 May) was the most
productive region this period and produced five X-class flares, and
seven M-class flares; the largest of which was an X2.8 flare at
27/0708 UTC. Region 3691 (N25, L=042, class/area=Ekc/480 on 27 May)
produced three M-class events and Region 3695 (N27, L=028,
class/area=Cao/30 on 01 Jun) produced a single M-class flare. Other
notable activity included a long-duration X1.4/2b flare at 29/1437
UTC from Region 3697, with accompanying Type II and IV radio
emissions, and an Earth-directed partial halo CME that arrived on 31
May. Additionally, an impulsive X1.0/2b flare at 01/1836 UTC and a long-duration M7.3 flare at 01/1939 UTC, both from Region 3697,
resulted in a CME that is likely to glance by Earth on 04 Jun.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
normal to moderate levels.

Geomagnetic field activity was at quiet and quiet to unsettled
levels throughout much of the period. An isolated period of G1
(Minor) geomagnetic storming was observed early on 31 May due to CME
activity.

Forecast of Solar and Geomagnetic Activity
03 June - 29 June 2024

Solar activity is likely to reach moderate and high levels
throughout the period, with M-class flares likely and a varying
chance for X-class flares through 29 Jun.

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) geomagnetic
storm levels on 04 Jun, and active levels on 05 Jun, due to the
anticipated glancing-blow arrival of the 01 Jun CME. Active
contidiions are expected on 09 Jun due to CH HSS influences. Quiet
and quiet to unsettled levels are expected to prevail throughout the
remainder of the outlook period.
