Much more likely: A Galactic Cosmic Ray - GCR - caused the bit flip. The sun was pretty quiet that day and it's hard to believe that it produced some GeV particles that day …

Here is a video with many large to very large CMEs recently observed by the SOHO LASCO C3 coronagraph bsky.app/profile/mark...

You can estimate the weight with measurements in coronagraphs. The average mass ejected is 1.6 billion tons. This CME is likely heavier as we could see a lot of dense material.

It is unstable, but it looks as if the plasma is precipitating from above onto both sides.

Well, you can try hiking there… That's the boundary between the positive and negative polarity sectors, or if you like, the magnetic equator. It's the source of slow solar wind and gives us clues about the possible deflection of CMEs (towards the dashed line).

Beautiful coronal mass ejection (not facing Earth)
