Last winter was unusually poor in Northern Lights, but the last few days were amazing. Night of April 5 to 6, 2010 was full of powerful displays. Two times in the night; the sky became a shiny colourful kaleidoscope. The Northern lights were over head dancing for two or three minutes at very fast rhythm, moving East West, changing from green to yellow, yellow to white, white to a unique pink-purple. We could see better than at in full moon night. This one is an overhead umbrella shape.
It has to be mentioned that in the post-processing I didn't increase colours' saturation. The post-precessing was mostly to remove the noise.
