The tree was hoisted into place on Friday on a midtown Manhattan plaza, next to a skating rink.
At the time, the temperature was inching into the upper 50s.
The tree was donated by Peter and Stephanie Acton of Mahopac (MAY'-oh-pak), N.Y. It was cut down Thursday in the backyard of their Putnam County home.
Peter Acton, a New York City firefighter, was a 9/11 responder.
The Rockefeller Center tree scout discovered the family's spruce this year, on Sept. 11.
The lighting ceremony is Nov. 30.
