Latest PSI eclipse prediction
This image shows a prediction of what we can expect to see during the 12 August 2026 total solar eclipse, as viewed from Palencia, Spain. During a total eclipse, the Moon completely covers the Sun, shown here as the black circle at the centre of the image. This revealing the Sun's faint outer atmosphere, the corona, seen here as white streaks extending from the centre.
Totality reveals structures in the corona that are shaped by the Sun's magnetic field. This means that eclipses provide a rare opportunity to test whether computer simulations accurately capture the Sun's changeable magnetic environment.
To make this kind of prediction, Predictive Science Inc. uses a complex computer model of the Sun's magnetic field. Among the many inputs for this model are measurements taken by the ESA-led Solar Orbiter mission.
The predictions are updated every few hours, based on the latest measurements available. Click here for the latest predictions.

Unevenly distributed white streaks extend radially outward from the edge of this circle, simulating the Sun's corona as revealed during the 12 August 2026 total solar eclipse.
