A Total Solar Eclipse of Saros 145

A darkened sky holds bright planet Venus, the New Moon in silhouette, and the shimmering ap990819.html in this image of a total solar eclipse. A composite of simultaneous telephoto and wide angle frames it was taken in the path of totality 18 years ago, links.ifttt.com/wf/click?upn=jGHDfwvrKDxaofcg5GVuln86JGtL0lfRbeoDIo3IzsU-3D_ZK9XMfi1BLECKI0Cqx7-2FPc-2FHGjieojwgjC-2B2xBKvDh5QAbIxj6Vqhdvg-2FdUTFVfwzqXvpsQbSYFL97GmMVflBI6I-2BrRlpYa-2BVddjxbm3-2B22.... That particular solar eclipse is a member of Saros 145. Known ap130120.html from observations of the Moon's orbit, links.ifttt.com/wf/click?upn=jGHDfwvrKDxaofcg5GVulu6R7U84jmJM4bguT3yGiYk-3D_ZK9XMfi1BLECKI0Cqx7-2FPc-2FHGjieojwgjC-2B2xBKvDh5QAbIxj6Vqhdvg-2FdUTFVfwzqXvpsQbSYFL97GmMVflBI6I-2BrRlpYa-2BVddjxbm3-2B22... when the Sun, Earth, and Moon will return to the same geometry for a solar (or lunar) eclipse. The Saros has a period of 18 years, 11 and 1/3 days. Eclipses separated by one Saros period belong to the same numbered Saros series and are very similar. But the path of totality for consecutive solar eclipses in the same Saros shifts across the Earth because the planet rotates for an additional 8 hours during the cycle's fra ctional day. So the next solar eclipse links.ifttt.com/wf/click?upn=jGHDfwvrKDxaofcg5GVuluAz8RrNkk-2BoKBXK8rjVpn4-3D_ZK9XMfi1BLECKI0Cqx7-2FPc-2FHGjieojwgjC-2B2xBKvDh5QAbIxj6Vqhdvg-2FdUTFVfwzqXvpsQbSYFL97GmMVflBI6I-2BrRlpYa-2BVddjxbm3-2B... will also be a total eclipse, and the narrow path of totality will track coast to coast across the United States on links.ifttt.com/wf/click?upn=jGHDfwvrKDxaofcg5GVulszApUrtMH8s-2FXliZ30afRU-3D_ZK9XMfi1BLECKI0Cqx7-2FPc-2FHGjieojwgjC-2B2xBKvDh5QAbIxj6Vqhdvg-2FdUTFVfwzqXvpsQbSYFL97GmMVflBI6I-2BrRlpYa-2BVddjxbm3-2B....
