Made any Christmas plans yet? How about a trip to the Arabian Peninsula to watch a ‘Ring of Fire’ as most of the Sun is dramatically eclipsed by the Moon at sunrise while North Americans are enjoying their last few hours of Christmas Day? Now just 300 days out, intrepid eclipse-chasers are already making plans because this won’t just any partial solar eclipse. At daybreak on December 26, 2019, there will be an annular solar eclipse, which occurs when a ‘micromoon’ covers most of the Sun. Though not quite large enough in the sky to cover the whole of the Sun’s bright disc (as happened during the total solar eclipse on August 21, 2017 in the U.S.) this eclipse promises to be a special event.
