Coronal Hole Lifetimes Studied with the McIntosh Archive
Abstract
Through long term observation we can see that coronal holes positions and lifespans change dramatically over a solar cycle, but tend to repeat those patterns from solar cycle to solar cycle. By looking at the positions and lifespans of different coronal holes we can see that they are interconnected with the extended solar cycle (22yrs) and the activity cycle (11yrs). The positions of low latitude coronal holes that remain for over one rotation demonstrate a dramatic similarity to both sunspots and plage in terms of their positions on the sun over a solar cycle, forming the classic butterfly pattern.
