Looks like 2012 has started rather well and we were rewarded with two Auroras in a week ( January 16th and 22nd) visible from Southern Coast of Australia. The color of the aurora depends on which atom is struck by solar wind, and the altitude of the meeting. Green - oxygen, up to 150 miles in altitude Red - oxygen, above 150 miles in altitude Blue - nitrogen, up to 60 miles in altitude Purple/violet - nitrogen, above 60 miles in altitude ( from ) Time lapse motion control performed with Dynamic Perception Stage Zero.
