Will Solar Cycle 24 Be 17 Years long?

Read an interesting Blog today about three Norwegian scientists who used historical solar green corona emissions data to predict that Solar Cycle 24 will be 17 years long, 4.5 years longer than Solar Cycle 23:


The Norwegian study referred to in the Blog is available for download here:


We are currently in Cycle 24 which has, thus far, been lackluster as far as sunspots and solar flux go.  I haven’t read the Norwegian study in detail, yet – I’m curious to know when the Norwegian authors think Cycle 24 will peak and at what level of solar activity and how they reached their conclusions.

My fingers are crossed for a vigorous Cycle 24 peak as it would be nice to have a bout or two (or three) of temperate latittude F2 propagation on 50-MHz before sliding down to the Cycle 24/25 trough!
