NASA’s Solar Dynamics Observatory (SDO) zoomed in almost to its maximum level to watch tight, bright loops and much longer, softer loops shift and sway above an active region on the sun, while a darker blob of plasma in their midst was pulled about every which way (May 13-14, 2014). SDO studies how solar activity is created and how space weather comes from that activity. Measurements of the interior of the Sun, the Sun’s magnetic field, the hot plasma of the solar corona, and the irradiance that creates the ionospheres of the planets are our primary data products -- source link
