月亮投下阴影

NASA’s Earth Polychromatic Imaging Camera aboard the Deep Space Climate Observatory (DSCOVR) captured the lunar shadow during the Oct. 14 annular solar eclipse. The sensor provides frequent global views of Earth from its position at Lagrange Point 1, a gravitationally stable point between the Sun and Earth about 1.5 million kilometers from Earth.

DSCOVR is a space weather station that monitors changes in the solar wind, providing space weather alerts and forecasts for geomagnetic storms that could disrupt power grids, satellites, telecommunications, aviation and GPS.

10月14日日环食期间，NASA搭载在深空气候观测站（DSCOVR）上的地球多色成像相机拍摄到了月影。该传感器从拉格朗日点L1的位置提供地球的频繁全球视图，拉格朗日点L1是太阳和地球之间的引力稳定点，距离地球约150万公里。

DSCOVR是一个太空气象站，监测太阳风的变化，为可能破坏电网、卫星、电信、航空和GPS的地磁风暴提供空间天气警报和预报。
