Description

The sunspot butterfly diagram is a well known pattern, where the location of sunspots is shown to drift from higher latitudes to lower latitudes over a solar cycle, correlating with solar activity. The Fermi-LAT has been operational since 2008, collecting a full solar cycle of gamma photons from the sun over the time period of 2008-2021. We take a first look at the distribution of these high-energy gamma events and their correlation with surface features of the Sun, such as the appearance of sunspots over this time period.
