New York ? Joseph Maurer, whose daughter died in the Sept. 11 terror attack on the World Trade Center, said he and his family would stay away from their television set on Monday.

“They’re going to keep showing the buildings collapsing, and we’re not really all that interested in seeing that part of it,” Maurer said.

Monday, exactly six months since the attacks, was to be observed with prayers and reflection, the dedication of a scarred memorial and a tribute of twin beams of light. At the same time, many victims’ relatives say Monday will be filled with awful memories.

Maurer, a retired firefighter from Brooklyn, lost his daughter, Jill Campbell, in the attack, as well as a dozen firefighter friends. He said his family was considering going to ground zero for the lighting of the beams, which are meant to evoke the destroyed towers.

The city’s schedule was to begin at 7:30 a.m. CST, with police officers gathering outside precincts as the names of the 23 officers killed in the World Trade Center attack are read aloud. The day was to end after dark with the ceremonial lighting of the Tribute in Light, two towers of light aimed skyward into the night sky from a spot near ground zero.

The Tribute in Light will consist of 88 high-powered beams of light. The display was created by two arts organizations and will be displayed until April 13. The estimated $10,000 worth of electricity is being donated by Con Edison.

City officials planned to dedicate another temporary memorial, a 5,000-pound steel-and-bronze sculpture called “The Sphere,” near ground zero in Battery Park.

Mayor Michael Bloomberg was to introduce a moment of silence at 7:46 a.m. CST Â the time that the first of two hijacked airliners slammed into the trade center. Gov. George Pataki, former Mayor Rudolph Giuliani and some victims’ relatives were to speak before another moment of silence at 8:03 a.m. CST, the time that the second plane hit.

“The Sphere,” which stood in the fountain of the trade center plaza, was gashed and partially crushed by falling debris. It was created in 1971 by artist Fritz Koenig and originally was dedicated as a monument to world peace through world trade.

Bloomberg said the globe probably would serve as a centerpiece for a permanent memorial.

Also today, flags at Port Authority facilities were to be flown at half staff, honoring the 84 employees lost, 37 of whom were Port Authority police officers.

Holli Silver, whose husband, David, died in the trade center, said she would skip the ceremonies, instead spending the day with her infant and toddler, away from news.

“Look at how we have to live our lives,” Silver said. “Every morning you wake up and wonder if they’ll find another (body) part that day. I don’t want the world to forget, that’s for sure, so if this means people will pay attention, that’s fine. But as far as for me, six months is still a living hell.”
