Scientists have used Solar Orbiter’s EUI camera in a new mode of operation to record part of the Sun’s atmosphere at extreme ultraviolet wavelengths that has been almost impossible to image until now. This new mode of operation was made possible with a last-minute ‘hack’ to the camera and will almos
Solar Orbiter’s Extreme Ultraviolet Imager returns high-resolution images of the structures in the Sun’s atmosphere. Scientists call this region the corona. During EUI’s construction, a last-minute modification to the safety door on the front of the instrument has allowed it to see deeper into its target region than originally specified.
This movie shows an ultraviolet image of the Sun’s corona taken using the EUI occulter. An ultraviolet image of the Sun’s disc has been superimposed in the middle, in the area left blank by the occulter. The image of the Sun’s disc has been taken by’s STEREO mission, which happened to be looking at the Sun from almost the same direction as Solar Orbiter at the same time, so the features on the surface have a good correlation to the features in the corona.
