While we are waiting for the total solar eclipse of the 8th of April 2024, we can have a look at some special images of the solar corona.
The first pictured here, using multiple images and digital processing, is a detailed image of the Sun’s corona taken during the April 20, 2023 total solar eclipse from Exmouth, Australia. In the darkness of a total solar eclipse the light of the solar corona is easily visible. Normally overwhelmed by the bright solar disk, the expansive corona, the sun’s outer atmosphere, is a special sight. But the subtle details and extreme ranges in the corona’s brightness, although discernible to the eye, are nowadays discernible thank to photograph digital processing.
Another impressive image of the unwrapped from the complete circle of the eclipsed Sun’s edge to a rectangle and mirrored, the entire solar corona is shown during the 2017 eclipse (bottom) seen from Jackson Hole, Wyoming, and the 2023 eclipse from Exmouth, Western Australia.
