SDO 2014 spring eclipse season has begun

Twice every year, around the time of the equinoxes, Earth can pass directly between the Sun and NASA's Solar Dynamics Observatory (SDO), producing a series of beautiful eclipses. For the next 3 weeks the Earth will pass between SDO and the Sun around 07:30 UTC each morning.  These eclipses can last up to 72 minutes in the middle of an eclipse season.

SDO's first vernal eclipse season began on February 27, producing a near-total blackout of the sun.

Active regions 1981-1984 are further to the right and are hardly affected by the Earth, although they soon disappear behind the Earth.

Eclipses are one of SDO's largest data holes. But the orbit gives them 24/7 access to the data flow. So far SDO has received 98% of the data.
