Sunspots and the Sunspot Cycle

Sunspots and the Sunspot Cycle

Overview
Locations

What are sunspots and why does the sunspot number vary on an eleven-year cycle. As we enter what promises to be one of the deepest sunspot minimums in the last 100 years we'll discuss the nature of sunspots and the effects they have on the Earth's atmosphere and the possible effects on our weather.

The Dibert-Roddick Planetarium is located in the Franklin Science Center on the campus of Shippensburg University.
