    April 5, 2019 - Scientists charged with predicting the Sun’s activity for the next 11-year solar cycle say that it’s likely to be weak, much like the current one. The current solar cycle, Cycle 24, is declining and predicted to reach solar minimum - the period when the Sun is least active - late in 2019 or 2020.

    Solar Cycle 25 Prediction Panel experts said Solar Cycle 25 may have a slow start, but is anticipated to peak with solar maximum occurring between 2023 and 2026, and a sunspot range of 95 to 130. This is well below the average number of sunspots, which typically ranges from 140 to 220 sunspots per solar cycle. The panel has high confidence that the coming cycle should break the trend of weakening solar activity seen over the past four cycles.

    “We expect Solar Cycle 25 will be very similar to Cycle 24: another fairly weak cycle, preceded by a long, deep minimum,” said panel co-chair Lisa Upton, Ph.D., solar physicist with Space Systems Research Corp. “The expectation that Cycle 25 will be comparable in size to Cycle 24 means that the steady decline in solar cycle amplitude, seen from cycles 21-24, has come to an end and that there is no indication that we are currently approaching a Maunder-type minimum in solar activity.”

    They come and they go.
    I just ordered my kx2.

    Just have to make the QRP operations - more efficient ;)

    Time to build that 3CW20000A7 propagation maker:eek: That blower is just for the 750W filament.

    That display was built at a local college to demonstrate water cooling and the tube has never had HV applied. Honestly, I dont have the cojones to mess with that much power:D:rolleyes:

    Doom and gloom everywhere, but since FT8 started I'm perfectly happy operating under these dismal conditions. When cycle 25 peaks will we get bored operating all the easy DX??

    I attach a graph of global temperature swings over 4500+ years. The two variables used for that analysis are solar radiation and volcanic activity. This was done in 2011, and they correctly predicted some cooling between then and 2019. They do project a Hot Dry cycle moving ahead to 2038....but then the topic of this thread is a weak cycle 24, and cycle 25 with a long space in between. Maybe we continue to cool for a while?

    630M should be doing good.
