Powerball winner bought $473 million ticket in Arizona but hasn't claimed it yet

A single lottery ticket sold in Arizona won Wednesday's Powerball jackpot of $473.1 million.

The winning numbers in the drawing were 11, 36, 61, 62 and 68. The Powerball number was 4. Strong sales caused the jackpot to climb beyond estimates.

The ticket was bought at a QuikTrip convenience store in Gilbert, a suburb of Phoenix, John Gilliland of the Arizona Lottery said. The identity of the winner is not yet known, but they can choose to take a lump sum payment of $283.3 million.
