Region 3664 not done yet! Produces X8.7 flare...largest of the solar cycle!
published: Wednesday, May 15, 2024 14:28 UTC

Region 3664 produced yet ANOTHER X-ray flare as it moves beyond the Western solar limb!! This time, it was an X8.7 flare, the largest of this solar cycle! Due to its location, any CME associated with this flare will likely NOT have any geomagnetic impacts on Earth. As always, stay tuned to our website for updates!  **CORRECTED for magnitude 8.7, not 8.8**
