 Sun spot

Jean-Paul Desgrees, Chartres, France, 13 June 2020

Jean-Paul says: “The Sun has fascinated me since 1973 when I was secretary of the solar commission of the Astronomical Society of France. It’s in a period of low activity in its 11-year cycle at the moment, so when I captured this spot I thought I’d share it with you.”
