Solar minimum?

We are approaching the next solar minimum. Such periods are characterised by very low sunspot numbers for a long time. We have already had many weeks without sunspots. We can expect more "quiet sun" weeks until we climb on the upward slopes towards the peak of cycle 25. At the moment we are looking at 2020 for the next minimum.
