NOAA South Pole Live CameraHorizon and Amundsen-Scott South Pole Station taken every 15 minutes. "In order to preserve the life of the camera, it is tilted down onto the snow when the sun is in the field of view, which occurs for several weeks around sunset (March) and sunrise (September) when the sun marches in a circle above the horizon. From mid-April until mid-August the moon and the aurora australis provide the only natural lighting."
INSTAAR Tundra-Cam IIYou can control which way to look. "The Tundra-Cam II is located within a Biosphere Preserve (designated by UNESCO, the U.S. State Department, and the U.S. Forest Service), which has also been selected by the National Science Foundation as the alpine tundra component of the Long-Term Ecological Research (LTER) program."
