The moon crossed between NASA’s Solar Dynamics Observatory (SDO) and the sun, a phenomenon called a lunar transit.

A lunar transit happens approximately twice a year, causing a partial solar eclipse that can only be seen from SDO’s point of view. Images of the eclipse show a crisp lunar horizon, because the moon has no atmosphere that would distort light. This image shows the blended result of two SDO wavelengths – one in 304 wavelength and another in 171 wavelength.
