ST. ANTHONY, IDAHO – When the last bright bit of light disappeared through the dark eclipse glasses and the sun winked out – turning the day dark – everybody in the park cheered. What had been baking-hot sun had gradually gotten cooler and cooler, and now, all of a sudden, it was dark – and cold. No one was left in the water, where earlier happy kids and parents had been splashing and frolicking. And the shrinking sliver we’d all been watching through our eclipse glasses had completely disappeared – there was just darkness there. Instead, as we all took off our glasses, we saw a black disk in place of the sun, surrounded by a bright, clear-white corona; points shot off it at the upper left and lower right.
