Photos taken by a USA TODAY photographer early Sunday afternoon show no visible flame in the Olympic cauldron at the medals plaza outside the stadium, where it was lit during the opening ceremony on Feb. 4. The flame traditionally remains lit for the entire duration of the Olympics.
The International Olympic Committee referred questions about the flame to the Beijing 2022 organizing committee, whose spokespeople did not immediately reply to requests for comment.
The Olympic flame is one of the most recognizable symbols of the Games, beyond perhaps the Olympic rings. It is lit before every edition of the Olympics at a special ceremony in Olympia, Greece, using "the ancient method of the sun's rays in the parabolic mirror," according to an IOC document.
The flame is then transported to the host city through the ballyhooed torch relay, which can take several months and involve thousands of torch bearers.
