Get ready for the 2024 April 8th solar eclipse : read the guide.
Solar eclipses are rare due to specific conditions. On October 14 2023, an annular solar eclipse will be visible from the United States. We, at Vaonis, plan to record it with our smart telescopes Vespera and Stellina. Before the event, here’s some information about the phenomenon. We will discuss the observation conditions and the different zones from where you can observe an eclipse.
The path of totality
During a solar eclipse, the Moon’s shadow covers the Sun, creating a shadow zone where the phenomenon can be observed. When a total eclipse occurs, the area where the eclipse can be seen is referred to as the “path of totality”.

The movement of the Moon’s shadow on Earth is from West to East. The term used to describe the projection of the shadow on Earth throughout its journey is “shadow band.” The width of the shadow band fluctuates based on the Moon’s apparent size, and can extend to 250 kilometers if the apparent diameter is significant.
To observe solar eclipses, it is recommended to position oneself along the path of totality
