Lots of nice links, guys! Thanks.

(My astronomy classes are about to begin studying the Sun--as an average yellow dwarf star--on their way to spectrography and stellar evolution.) As always, I appreciate any help (especially nice resources like this) that I can get!

And, as you may imagine, the kids (high-schools seniors, but still "kids" like the rest of us) love the PST! Lots of ooohs and ahhs!
