September 2025 solar eclipse, no matter if it was partial or not.
The initial eclipse trajectories were established using a method known as Besselian elements. These consist of a series of parameters based on the premise that spherical orbs such as the sun possess a constant radius. Regrettably, some of the utilized figures are obsolete, which results in solar paths displayed on a map being imprecise. The initial data suggests the sun’s solar radius measures 959.63 arc seconds — approximately 432,000 miles — whereas the actual measurement is closer to 959.95 arc seconds, a variation of plus or minus 0.05 arc seconds. On the Earth’s surface, this variation can displace the path of totality by roughly 2,000 feet in different directions. At the time of an eclipse, if you’re 2,000 feet away from the center and wish to catch sight of a total solar eclipse, it won’t be feasible. It’s easy to see why this poses an issue. However, don’t worry. You can utilize the maps from the Basselian Elements team to accurately follow the trajectory, and they even provide a mobile application.
