Forecast of Solar and Geomagnetic Activity
13 May - 08 June 2024

Solar activity is expected to remain at moderate to high levels
through the forecast period. Region 3664 will rotate off the visible
disk by 14-15 May, and another 10 regions will depart the visible
disk between 16 and 23 May. This will lead to a relative lull in
activity compared to the past week. However, a couple of regions
rotating on will maintain the potential for at least moderate
activity. Region 3663 is expected to return on the 23rd and Region
3664 on the 28th of May, with a significant increase in the threat
of high activity.

There is a chance for proton events at geosynchronous orbit,
particularly with the return of Region 3664. This doesn't
preclude the possiblity of an event in the days leading up to the
23rd, but the risk will increase with each day Region 3664 moves
across the visible disk.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at moderate levels throughout the period.

Geomagnetic field activity is expected to be at minor storm levels
to being the period, with a lingering chance of moderate to strong
levels through the 14th. A relatively quiet period follows,
interupted by coronal hole high speed stream activity between 23 May
and 3 June.
