Solar Annular Eclipse “Ring of Fire” - 26th December 2019; Saudi Arabia -

al., A. Elmhamdi et . 2020

Since ancient times, Solar eclipses are considered to be fascinating natural phenomena during which the Moon obscures fully or partially the Sun’s disk. Annular eclipses are relatively rare, and occur when the Moon covers the Sun's center, leading to a visible brilliant Sun’s outer edges with a magnificent annulus ring-shaped, dubbed also “ring of fire”. Here we report some observational data of the annular last solar eclipse of the decade, 26th Dec. 2019, which began primary in Saudi Arabia, visible along a narrow path in other countries in the globe Eastern Hemisphere. Our observations are taken from the major urban region in the Al-Ahsa oasis in the eastern province of Saudi Arabia, located on the centre eclipse path line, namely in the Al-Hofuf city (at the Four Mountains desert area). The annularity occurred at sunrise and last roughly 3 minutes, immersed in a sandy horizon, making the view of the events particularly exceptional and attractive for astronomers and sky-watching enthusiasts.
