SDO captures images of Lunar transit, on July 26, 2014, from 10:57 a.m. to 11:42 a.m. EDT. Image Credit: NASA/SDO
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.
