Officials are set to identify the jackpot winner during a news conference Tuesday afternoon. They say the winner won't be in attendance.
The winning ticket was sold at a Gateway Newsstand in the city's Buckhead area. A second winning ticket was sold at a gift shop in San Jose, Calif.
The winning numbers were: 8, 14, 17, 20, 39; Mega Ball 7.
The jackpot is the second-largest lottery prize in U.S. history. It started its ascent Oct. 4. Lotto officials say 22 draws came and went without winners.
