The numbers did increase by a small amount, and the aurora picture is a much deeper orange the last time I looked. So, it appears that deteriorating DX conditions are a precursor to increased solar activity as reflected in the WWV reports. That's interesting, but a bit sad that DX can predict solar conditions, rather than the other way around. It may well be that the TA/TP MW skip is a far more sensitive indicator of the solar activity than even the observational instrumentation attached to the NOAA/WWV reports.
