2023 - On October 14, 2023, the famed “Ring of Fire” will encircle a darkened Moon during a spectacular annular eclipse. This special type of partial solar eclipse occurs when the Moon is too far from Earth to cover the Sun completely. The Sun's corona is not visible during an annular eclipse.
2024 - On April 8, 2024, the Moon will completely cover the Sun during an awe-inspiring Total Solar Eclipse. Observers within the path of totality will witness the sun’s dazzling corona, observe the “diamond ring” effect, and see day turn to night.
