The Solar Dynamics Observatory, Our New Eye on the SkyThe solar photon output, which was once thought to be constant, varies over all time scales from seconds during solar flares to years due to the solar cycle. These solar variations cause significant deviations in the Earth and space environments on similar time scales, such as affecting the atmospheric densities and composition of particular atoms, molecules, and ions in the atmospheres of the Earth and other planets. Presented and discussed will be examples of current data from satellites that have preceded SDO such as TRACE, SOHO and TIMED that show how we can trace the origins of solar activity from inside the Sun, though its atmosphere, then all the way to the Sun's influence on the Earth and other objects in the solar system. The presentation will continuously emphasize how the Solar Dynamics Observatory (SDO), the first satellite in NASA's Living with a Star program, is going to improve upon these current observations and provide further insights into the variable Sun and its Heliospheric influence.
