Earth, Lunar Transits Observed On Same Day By NASA’s SDO
2013-03-12 10:01:36

NASA On March 2, 2013, NASA´s Solar Dynamics Observatory (SDO) entered its semiannual eclipse season, a period of three weeks when Earth blocks its view of the sun for a period of time each day. On March 11, however, SDO was treated to two transits. Earth blocked SDO´s view of the sun from about 2:15 to 3:45 a.m. EDT. Later in the same day, from around 7:30 to 8:45 a.m. EDT, the moon moved in front of the sun for a partial eclipse. When Earth blocks the sun, the boundaries of...
