The SDO spacecraft is in another eclipse season as of Feb. 6, 2019. This begins a several week period when the Earth briefly blocks SDOâ€™s view of the Sun each day. In fact, because SDO orbits above the Mountain Time zone, the Earth passes between SDO and the Sun at about 7:20 UT (12:20 am MT) each orbit. Eclipses are due to SDOâ€™s circular geosynchronous orbit some 22,000 miles above Earth. At the speed we are showing the frames, the eclipse is only a flicker. The still image shows that the edge of Earth, here about halfway across the Sun, looks quite rough due to the absorption of the 304 Å EUV light by our atmosphere.
