Partial Solar Eclipse Coming to N.America
mblase writes: "Space.com has the goods on the upcoming June 10 partial solar eclipse, the only North American eclipse this decade. Greater eclipsing occurs in the South, and Midwesterners and Texans will get the best show when maximum eclipsing occurs near sunset, when the sun appears largest. A good excuse to teach any young children you know some basic astronomy. (Remember, use pinhole cameras, never look directly at the sun, yadda yadda yadda.)"
Diskettes transmit too much IR and provide an inferior image, according to this Sky and Telescope article by Ralph Chou, a professor of optometry. Don't fool around, get a #14 shade from a welding supply shop. They're cheap, convenient, and reliable. Mine is a 4x5-inch plate of black ceramic material that turns the Sun a lime green color. When I bought it, the guys at the shop said, "Yeah, we got a few of those left over from the last eclipse. Nobody uses 'em for welding, they're too dark!"
