On 2025/02/24 a 2nd, larger proton event started ~22 UT, exceeding the S1 level (37.1 pfu).

It was caused by the big CME associated with an M3.9 flare, peaking at 23:02UT. As this video shows, the flare was again from behind the limb. It was likely X-class if observed on disk.

This is a screenshot of solarnews.nso.edu/sdo-iris-out... . I will not be able to post AIA near real-time images for some time, but only convey the updates from JSOC.

Unfortunately, this platform seems to compress videos more cruelly than others. Perhaps not good for scientific communications at least for now.

Tri-color movie of AIA 211Å, 193Å, 171Å running difference images of the far-side (~30° behind-the-limb) eruption on 2024/11/21. It was a big eruption, dominated by the counterclockwise propagation over the limb, which indicates interactions of the wave with coronal structures.
