Solar eclipse chasers have good reason to hope for a particularly spectacular sight on April 8 when the moon briefly passes in front of the sun.
A team of scientists is using supercomputers and extra-fresh data to predict the appearance of the sun's outer atmosphere, or corona.
The exercise allows scientists to test their understanding of how the sun's magnetic field governs the star's atmosphere.
The team is continuously updating the prediction of the corona appearance as new data come in, a new challenge compared to previous approaches.
