W6LG Discusses Propagation at the Bottom of the Sunspot Cycle [ Video ]

Will there be any DX at the bottom of the sunspot cycle? What resources are there for chasing DX? When is the bottom of the current cycle?

The solar cycle or solar magnetic activity cycle is the nearly periodic 11-year change in the Sun’s activity (including changes in the levels of solar radiation and ejection of solar material) and appearance (changes in the number and size of sunspots, flares, and other manifestations).
They have been observed (by changes in the sun’s appearance and by changes seen on Earth, such as auroras) for centuries.
The changes on the sun cause effects in space, in the atmosphere, and on Earth’s surface. While it is the dominant variable in solar activity, aperiodic fluctuations also occur.
