Are sunspots the key to answering the decades-old solar coronal heating problem? The authors of today’s paper observe a few sunspot groups to find out.
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.
How do large sunspot groups affect long-term and short-term variations in solar activity?
