David Yu, San Francisco photographer, got a splendid picture of last night's blue Moon. But not in San Francisco. He caught it just above the
California state capitol building in Sacramento.
Low in the sky, the Moon is a vivid reddish orange. I've never seen the Moon looking blue - and certainly not a blue "blue Moon". But I've often seen a Moon low in the sky looking red, orange or red orange, whether or not it was a "blue Moon".
