Hi Ashly, Here is an web page about the biggest sunspots on record http://spaceweather.com/sunspots/history.html Acording to that the largest sunspot group in the last 100 years or so was back in the 1947 There is a picture here: http://physics.usc.edu/solar/images/470407.large.jpg That is pretty big! Remember for scale that you can fit 109 Earths across the disk of the sun at the equator. Terry
