Solar Dynamics Observatory Sees Lunar Transit - On Jan. 30, 2014, beginning at 8:31 a.m. EST, the moon moved between NASA’s Solar Dynamics Observatory, or SDO, and the sun, giving the observatory a view of a partial solar eclipse from space. Such a lunar transit happens two to three times each year. This one lasted two and one half hours, which is the longest ever recorded. When the next one will occur is as of yet unknown due to planned adjustments in SDO's orbit.

SDO is the most advanced spacecraft ever designed to study the sun and its dynamic behavior. It provides images 10 times clearer than high definition television and more comprehensive science data faster than any solar observing spacecraft in history.
