During solar minimum, intense activity – such as sunspots and solar flares – subsides, and the suns's activity changes form. For example, during solar minimum, the sun can develop long-lived coronal holes. And during solar minimum, the effects of Earth's upper atmosphere on satellites in low Earth orbit changes too. There are unique space weather effects that get stronger during solar minimum. Find out these things and more, in this new NASA ScienceCast video.
