Forecast of Solar and Geomagnetic Activity
22 April - 18 May 2024

Solar activity is expected to be moderate levels
(R1-R2/Minor-Moderate), with a chance for X-class flare R3 (Strong),
over 22-27 Apr due to a plethora of productive sunspots rotating
towards the W limb. As those spots groups rotate off, solar activity
is likely to be a low levels with a chance for M-class (R1-R2),
through the remainder of the outlook period due to both developing
spots in the E hemisphere and the return of productive spot groups
on the farside of the Sun.

There is a chance for the greater than 10 MeV proton flux at
geosynchronous orbit to reach above the S1 (Minor) levels over 22-27
Apr due to the plethora of sunspots in the W hemisphere.

The greater than 2 MeV electron flux at geosynchronous orbit may
reach high levels on 22-25 Apr in response to geomagnetic activity
observed on 19 Apr.

Geomagnetic field activity is like to reach active levels over 22-24
Apr and 26-27 Apr in response to multiple coronal hole high speed
streams (CH HSSs). There is potential for combined influence of
coronal hole activity and multiple weak transients over 22-24 Apr.
Unsettled levels are likely on 25 Apr, 01-03 May, and 05-07 May due
to the anticipated return of multiple other weak CH HSSs. The
remainder of the outlook period is likely to be at mostly quiet
levels.
