Here in central coastal California at 0755 UTC I heard several minutes of a CW transmission that I believe is spy-related. It was around 20wpm, a little faster than I can reliably copy. Appeared to be number and letter groups--letters did not seem to be words or usual ham abbreviations, but my fast CW copy is marginal. Off at 0800 UTC.
