    Hi Chris, Check out this webpage for some data on the largest sunspots ever recorded; http://www.spaceweather.c...unspots/history.html

    The largest sunspot group recorded since 1991 occurred in March of 2001 and covered the same area as 15 Earths. The largest in the last century was almost 3 times larger than this one.
