Sunspots and Space Storms
Today’s astrobite dives into the differences between space weather and space climate and how sunspots affect both processes.
Old, New, Cyclic, and Ultra-Blue: Visualizing the Last 400 Years of Solar Activity
Historic observations of sunspot variability have improved our understanding of the solar cycle tremendously, but recent reanalyses of these data has yielded a conflicted view on solar variability within the past few centuries. Today’s paper shows how we can both better visualize existing historic data and where we can go next in understanding the long-term variability of our closest star.
