Upcoming Eclipses: 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.
