The sun emitted a mid-level solar flare which can disturb the atmosphere in the layer where communications signals travel. This disrupts the radio signals for as long as the flare is ongoing.
On May 17, 2013, the sun erupted with an Earth-directed CME that can reach Earth one to three days later and affect electronic systems in satellites and on the ground.
The Solar Physics Laboratory works to understand the Sun as a star and as the primary driver of activity throughout the solar system. Our research expands knowledge of the Earth-Sun system and helps to enable robotic and human exploration.
We develop innovative instruments and mission concepts, theoretical models, and techniques to access and analyze data. The Laboratory provides project scientists for NASA missions, assists with strategic planning and mission definition, and communicates research results to the international scientific community and the public.
