This recent post was on the fact that the Sun’s EUV emissions had fallen to solar minimum-like levels well ahead of solar minimum. The implication was that the Solar Cycle 24/25 minimum was either going to be very deep and prolonged, or that Solar Cycle 24 would be very short, which in turn would be strange for a weak cycle.
David provides extensive graphics to make his points at the link. He also included a model developed by a retired B52 Pilot Ed Fix that predicts minimum in 2017.

Figure 6: Ed Fix’s solar activity model
The model has the Solar Cycle 24/25 minimum in 2017. Solar Cycle 25 is predicted to be weak and short also. If events of the next year or so prove Ed Fix’s model to be correct, then it will be as significant as the results of any of the expeditions to observe solar phenomena over the last three centuries, but we get to watch in real time.
2017 will be an interesting solar year, tracking the validity of Ed Fix’s model. Are we going to reach minimum by the end of 2017? Your thoughts?
