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.
FWIW the "industry sources say" line on the incident is that it occurred on 30 October[1], so further back than ten days ago but of course there may have been other CME incidents at that time.
The European Agency Aviation Safety Agency [2] instruction describes the characteristics of the incident but not the date.
