Solar radiation like solar wind, or sunlight? They don’t say.

“Analysis of a recent event”

I presume they mean a Coronal Mass Ejection.

There was a very large CME ten days ago. The NOAA scale had predicted a high likelihood of disruptions, and had specifically suggested that spacecraft and high altitude aircraft could be impacted.

I feel like the event was something that happened to a plane. That said, I wouldn't think sunlight would be penetrating to the chips running the plane.

Would guess "cosmic rays". Sun Microsystems had a batch of UltraSparc servers that were very sensitive to it, and it was a big issue.
