sunspots
we watched a documentary last night on sun spots & what physicists propose they may be, how they affect and are affected by the sun, and other various theories they each back. notice the size of the earth (fig.1) in comparison to the sunspots... sunspots are relatively cooler than their surroundings, hence their darker color. in 1859, a powerful sunflare directed towards earth, interrupted the telegraph service & caused visible aurora borealis in havana, hawaii, and rome. again in 2003 there was another sunflare, this time it was captured with satellites. supposedly they can be seen from earth, without use of a telescope, but are "blindingly bright."
