Event Watchlist
Space weather events linked to the current alerts. These are the underlying solar and geomagnetic events that triggered the notifications above.

No linked events were resolved for the current alerts.

About the watchlist

SWPC alerts don't carry DONKI activity IDs, so they appear in the alerts column but won't have linked events here. DONKI alerts with resolvable activity IDs will show their related events above.
