April 2024 Eclipse over Ontario & Quebec
After doing an animation of the August 2017 eclipse over North America, I was asked to do a similar simulation of the April 2024 eclipse. The area of totality of this eclipse skirts just south of London Ontario, and Toronto, and just kisses the fine city of Montreal. As with the prior simulation, this viewer of this scene is travelling along with the Earth with the line of sight pointing at London. The viewers position with respect to the Earth is fixed, so the Earth rotates below the viewer. The light purple shaded area with the straight edge is the 3D outer shadow cone of the Moon (or penumbra) travelling in space, within which someone looking at the Moon would see the Sun partially covered. The light gray elongated cone is the 3D inner shadow cone of the Moon (or umbra), in which a person looking at the Moon would witness the Sun being totally hidden. The dark purple teardrop on the surface of the Earth is where the penumbra comes in contact with the Earth. Here, people on Earth see a partial eclipse. The bright red is the area of totality, where the umbra meets the Earth’s surface, and observers experience a total eclipse.
