a.) A sunspot is a region on the sun's surface that is marked by intense magnetic activity, which inhibits convection, forming areas of reduced surface temperatures.


b.) The climate has an effect on the sunspot and changes them.


c.) It shows the latitiude of sunspot occurance versus time (in years).


d.) The number of sunspots reaches a maximum about every 11 years, but successive maxima have spots with reversed magnetic polarity. Thus the whole cycle is 22 years long.


e.) When there are significant sunspots, it makes the Earth colder.


f.) The next solar maximum is expected between 2011 -2012.


g.) Sunspots are observed with a land based telescope as well as ones on earth orbiting satellites.


h.) Dearborn Telescope
