The next solar cycle?

Many are suggesting the next solar cycle (cycle 25) will have a very small peak and that we may even be entering a period with very few sunspots, not unlike the Maunder Minimum of the late 1600s. Truth is no-one can be sure. If it happens, the best propagation on 10m will be summertime Es - no bad thing. We will have to use 10m mainly for local traffic - it is a big band and a good choice for this.

Sunspot "Maunder Minimum" continues

It goes on and on and on and on - still not a sunspot in sight and if anything the solar flux is dribbling downwards. See http://www.solen.info/solar/ from where the attached image is extracted (slightly edited). When, if ever in my lifetime, is the sun going to get moving again?

The VERY quiet Sun

Have you noticed how long we've been now without any sunspots? The graph at http://www.solen.info/solar/ suggests it's been almost 7 weeks now. A few months ago we were expecting the start of cycle 24 and some hopeful signs were emerging. Then things turned down again and it is doubtful we've started to enter cycle 24, although the slightly increased solar flux levels may be a hint. We can only wait and see.

At least the higher HF bands plus 6 and 4m will be livened up by sporadic-E shortly. If we were entering a long Maunder minimum (I doubt it) then the summer spor-E "sport" could be the best DX opportunities we'd get on 10 and 6m.
