Our Sun-watching satellite saw a lunar transit from space. 🛰🌓☀️

Our Solar Dynamics Observatory, or SDO, keeps a constant eye on the Sun from its vantage point in orbit around Earth. On Oct. 16, the Moon passed through SDO’s field of view for about 50 minutes, covering up to 44% of the Sun’s face at peak.

During this time, the Moon also happened to cover two of the spacecraft’s fine-guidance sensors, causing its view of the Sun to jitter slightly. SDO captured these images in a wavelength of extreme ultraviolet light. This kind of light is invisible to human eyes, and colorized here in gold.
