Someone in Brooklyn might be sitting on $1 million — but time is running out to claim the seven-figure winnings.

A winning Powerball ticket bought at a Brooklyn gas station last March is set to expire next Wednesday if the winner doesn’t step forward first.

“We’re still hoping that someone comes in to claim this ticket,” said Christy Calicchia, a spokeswoman for the New York Lottery.

The “golden” second-prize ticket hit five of the six numbers drawn that night — 11, 19, 24, 33, 51 — and only missed the #7 Powerball, a one-in-5-million chance.

The ticket was bought at Arnold’s Service Station on Linden Boulevard on March 18, 2014. As per the lotto’s rules, players have up to one year to claim their prizes before the money gets put back in the prize pool for future winners.

In the 2014 fiscal year, there was $54.2 million in unclaimed prizes in New York, according to Calicchia.
