Noctilucent clouds

Southgate News reports that noctilucent clouds were spotted over Washington state  on July 4th. For a long time I have had the view that these have something to do with the very long paths from Europe to Japan on 6m. These openings usually happen in June. If any openings are happening I am missing them.
