The Western US was treated to a rare Annular Eclipse tonight. It was already dark here but I followed it on the internet. I captured the image above while watching on my iPad. At the time of my screen capture the Moon covered about 94 percent of the Sun's surface. The eclipse started in Asia and spread across the Pacific Ocean to the Southwestern US. The most recent eclipse to occur in the US was back in 1994 and it will be 2023 before our mainland sees another.
