Strange 'Blue Auroras' Sighted

Space Weather News for Oct. 27, 2017 http://spaceweather.com https://www.facebook.com/spaceweatherdotcom STRANGE 'BLUE AURORAS' SIGHTED: Last night, strange bands and rings of blue light appeared over parts of Scandinavia and Russia. Was it a weird type of aurora? No geomagnetic storm was in progress. The explanation may be a barrage of missiles fired during an overnight Russian war game, spreading a blue-glowing cloud of rocket exhaust around the Arctic Circle. Photos and more information are highlighted on today's edition of Spaceweather.com. Remember, SpaceWeather.com is on Facebook!
