NIGHT-SHINING CLOUDS IN THE USA: High above Earth, bright clouds of frosted meteor smoke are spilling over populated areas of Europe and--for the first time this season--the USA. During the 4th of July holiday, observers in Washington state spotted night-shining (noctilucent) clouds bright enough to see even from urban-lit places like Seattle. This could signal a spread of the clouds to more states which, in years past, have been sighted as far south as Colorado and Utah. Visit Spaceweather.com for pictures and observing tips.
