Aurora ViewingThe best time to watch the "Northern Lights" is between December and March. This is when the nights are longer and the skies are darker. The Aurora is more active late at night or early in the morning, because the sky is clear and the air is chilly. Displays of the Aurora include ribbons of light that shimmer in the sky that lasts for hours on end. These ribbons look like glowing, dancing curtains of green, yellow and orange or dark red colors. The altitude of it's lower edge is 60 to 70 miles above the earth. Scientists think the Aurora is caused by solar winds that flow across the Earth's upper atmosphere, hitting molecules of gas and lighting them up like a neon sign. Even so, the rarest and most famous Aurora was a red Aurora that was sighted on February 11, 1958. |
