Coronal Emission

Here we show movies of predicted EUV and soft X-Ray emission from our coronal model. The four channels shown represent measurements taken by the Solar Dynamics Observatory (SDO) and the Hinode Spacecraft, both of which continuously observe the Sun from space.

Plasma in the corona emits naturally at these wavelengths, and each channel is sensitive to different temperatures in the corona. The left three channels, AIA 171, AIA 193, AIA 211 sample the corona from ~0.9-2.0 million degrees kelvin, while the XRT Ti-Poly channel has broad sensitivity for plasma above 2 million degrees.

The images below show the predicted coronal emission at the time of greatest eclipse (~13:20pm local time on August 21, 2017). Click on the images to see higher resolution versions.
