G3 Watch for 11 May
Increased Solar Flare Chances 8-10 May
Yet Another X Flare Observed
Thursday, May 09, 2024 16:11 UTC

Yet another strong (X2.2) flare was observed from Region 3664 around 0900 UTC today.

G3 Watch valid for 11 May
Thursday, May 09, 2024 12:07 UTC

Multiple CMEs erupted associated with flare activity from Region 3664 on 07-08 May.

Multiple R3 (Strong) HF Radio Blackouts Observed
Thursday, May 09, 2024 01:19 UTC

Both Regions 3663 and 3664 have produced X1 level flares as of the close of 08 May (UTC). The latest, pictured here, comes from Region 3664.

Large and Complex Sunspot Groups Lead to Increased Solar Flare Chances
Tuesday, May 07, 2024 16:14 UTC

Sunspot Region 3663's history of activity and the continued growth and complexity of Region 3664, are leading to increased solar flare risk.
