    Looking at Cycle 24 overall, it is a disappointment. Based upon the Aussie's "T-Index", (which I wasn't even aware of until reading K7RA's solar update this weekend), we're on the downside of the cycle already ( This index peaked in November 2011 at 103. Looking at previous cycles, In Cycle 19, the index was higher than the peak of the current cycle for 55 months running. During the next four cycles, this holds true for slightly shorter periods of time.

    But it's not as if we can do anything about it.

    Don't believe everything you read.

    Careful... All of the numbers on the decline side are predictions.. If you look at the previous cycles it's pretty common to have some highs and lows in the cycles. The predictions definitely don't follow the pattern.

    We'll just have to wait and see.

    Yes, that's true. There will be spikes in solar activity. But when you compare a graphs of Cycle 24 against Cycles 19-23, it is like comparing the Himalayas to the Appalachians.

    The graphs spanning the last three hundred years seem to show a longer, 100 year-or-so cycle, and it appears to me that we *may be* looking at several decades of cycle peaks below an daily average of 100.

    I remember in the previous cycle (23) driving to work in the morning and being in QSO with my friends in England and Ireland, with signals at S9 or better on a daily basis. I ran a little Uniden HR 2510 at a mighty 25 watts and a fiberglass whip for 10 meters. Lots of worldwide DX to be found. Australia in the evening was common too. In this cycle, there's not much to be had on 10 meters. 17 and 20 seem to be carrying most of the contacts. Cycle 24 is going to be known as "THE SUNSPOT CYCLE FROM HELL"
