On spaceweather.com I found in the report for Oct 6 2008, that over the Russian penninsula of Murmansk a green massive aurora wall is seen and photographed.
Murmansk is traditionally the home harbour of Russias nuclear fleet. http://map.rin.ru/cgi-bin/main_e.pl?Region=murmansk
My first impression was that green relates to something nuclear? Any input is welcome.
GREEN RAIN: Last night in Russia's Kolyskia peninsula, storm clouds gathered over Mt. Khibiny and the rain began to fall. Lo and behold, it was green:
Northern Lights posing as rain are a common occurance in this arctic part of Russia, where photographer Aleksander Chernucho keeps his Nikon D200 close at hand for midnight photo-ops. Shortly after the snapshot, shown above, the clouds pulled back revealing a bank of auroras so bright they turned the harbor waters as green as the sky.
Earth is exiting the solar wind stream that caused the display, but another stream is on the way. Sky watchers around the Arctic Circle should be alert for auroras when it arrives on Oct. 8th or 9th.
