On July 11, 2015 we received our first images in over three months from NASA's Solar TErrestrial RElations Observatory Ahead spacecraft, or STEREO-A. Since March 24, 2015, STEREO-A has been on the far side of the sun, where it has had to operate in safe mode, collecting and saving data from its radio instrument. While it was in safe mode, STEREO-A’s radio wave instrument collected and stored data continuously for four months. The mission is critically important for our capability to predict interplanetary space weather conditions. The two nearly identical observatories - one ahead of Earth in its orbit, the other trailing behind - have traced the flow of energy and matter from the sun to Earth.

The image below is from the Extreme Ultraviolet Imager, which collects images in several wavelengths of light that are invisible to the human eye. By triangulating the views from STEREO and solar observatories closer to Earth such as the joint ESA and NASA Solar and Heliospheric Observatory, scientists can create a full 3-dimensional model of coronal mass ejections, or CMEs.
