The new Moon passes between Earth and the Sun, casting its shadow onto Earth and causing a total solar eclipse. Where do you have to go to see it? More information is in Highlights for this season.
First sighting of the crescent Moon after new marks the start of Dhul-Qi'dah, the eleventh month of the Moon-based Islamic calendar. It should be visible with effort from most of the US, Central America, and most of South America just after sunset on the 3rd.
