Forecast of Solar and Geomagnetic Activity
25 March - 20 April 2024

The threat of high solar activity remains throughout the coming
week. Region 3615 (Fkc-BGD) is expected to remain on the visible
disk until March 29th-30th. The departure of Region 3615 is
anticipated to bring a period of low solar activity with a lingering
chance for M flares. Regions 3614 and 3615 are expected to return on
April 11th, increasing the potential for moderate to high activity.

Along with the high solar activity, there is a chance for another
proton event at geosynchronous orbit, with the greatest threat from
Region 3615 until it departs. The threat will decrease until the
region returns on April 11th.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at moderate to high levels during the forecast
period. The high levels are anticipated between March 28th-31st, and
again from 6-8 April in the wake of coronal holes.

The beginning of the forecast period is expected to see strong (G3)
geomagnetic conditions declining to mostly quiet conditions after
March 26th. Levels will increase to potentially minor (G1) levels
with the influence of a coronal hole high speed stream on April
3rd-5th. High speed streams on April 9th-11th and 19th-20th are
expected to bring less than minor (G1) storm conditions. The threat
of more CMEs and subsequent storms associated with Regions 3614 and
3615, or with new regions that emerge, remains.
