| Term: | SDO |
| Definition: |
The Solar Dynamics Observatory is a spacecraft with three experiments (instrument suites) designed to to study how solar activity is created and how space weather comes from that activity. The experiments are: 1) the Atmospheric Imaging Assembly (AIA); 2) the Extreme ultraviolet Variability Experiment (EVE); and 3)The Helioseismic and Magnetic Imager. Each of these observes the Sun simultaneously. SDO was launched on Feb 11, 2010 into an inclined geosynchronous orbit that permits full time viewing of the Sun. |
