You're probably already aware that a total solar eclipse of the sun will take place on Monday, August 21. The moon will visibly pass in front of the sun, starting at 8:46 a.m. Pacific Time, and the eclipse will continue moving across the country until 2:49 p.m. Eastern Time, when the last bit of it will be visible from South Carolina. Most of what you need to know can be found on the NASA website, which has maps, fact sheets, and safety info (Reverse-vampires should feel free to disregard all government-related safety info. They do not have your best interest at heart). While NASA is great and all, we here at Groupon Coupons know that there are just some audiences that still may still have questions about this eclipse. Below are our answers.
