The first total solar eclipse visible from the US mainland since 1979 occurs on August 21, 2017. Everyone with good weather conditions in the contiguous 48 states will get to take part in this rare celestial event. Those who live in the 70-mile wide path in 12 states, known as the zone of totality, will experience a complete solar eclipse. A narrow strip that crosses the US from Oregon to South Carolina will be plunged into full darkness during the day.
Arizonian observers outside this path will still see a partial solar eclipse where the moon covers part of the sun’s disk. Worldwide, the eclipse shadow covers less than 1% of Earth’s surface.
The eclipse will be viewable in Arizona starting around 9:15am, and will continue through around 12pm, depending on your exact location. This map from NASA can give you exact times to head outside on Monday.
Meteorologists can’t tell you with certainty what the weather will be in a certain location on the day of the eclipse, but Arizonians are likely to have clear skies. Just in case, pick a location with easy access to a highway system and plenty of parking that will allow you to relocate if weather threatens.
To be safe, make sure you have eclipse viewing glasses. They are available on a limited basis from local public libraries, and many event hosts will pass them out as well.
Join in the fun by going to one of these public events to learn more and enjoy the partial solar eclipse:
