• There are lingering uncertainties over those predictions as well as the size of the star and its expansive atmosphere. It’s unclear if the asteroid will obscure the entire star, producing a total eclipse. Rather, the result could be a “ring of fire” eclipse with a miniscule blazing border around the star. If it’s a total eclipse, astronomers aren’t sure how many seconds the star will disappear completely, perhaps up to 10 seconds.

    Sounds very interesting to anyone with a telescope in a cloud free area.
