The crazy Aurora of 17th March. For the first time this solar cycle the KP index reached level 9 (Scale of Aurora activity from 0-9). Luck was with me as it had been cloudy and stormy for weeks. Skies cleared up, wind died down and the Aurora was blazing. Never seen so many colors. Purple, red, green, pink and a hint of blue. This Solar storm seems to have created the right conditions for all these rare colors to pop out. It is Ionized Nitrogen that creates the rare blue color. I guess it take more energetic particles to get it to glow. via 500px orvaratli http://ift.tt/1CzNA6B
