The California mega millions has topped more than a half-a-billion dollars.

There was no winner Tuesday’s mega-millions drawing so the jackpot is now up to an estimated $548 million. The cash option is about $309 million.

The prize has been growing for 22 consecutive drawings since July 24

The next drawing is set for Friday, Oct. 12.

If someone wins Friday night’s $548 million jackpot, it would be the third biggest Mega Millions prize and the 9th largest in U.S. lottery history.
