AVM or The Anthem Veterans Memorial in Arizona is a special monument that was built in honor of the sacrifice and the service of the armed forces of the United States of America. The memorial is, however, “incomplete” 364 days per year. If one is interested to witness its majesty and to appreciate its beauty, he has to be at the place at a very specific time.

“At precisely 11:11 a.m. [PT] each Veterans Day (Nov. 11), the sun’s rays pass through the ellipses of the five Armed Services pillars to form a perfect solar spotlight over a mosaic of The Great Seal of the United States,” writes the community council of the city. “The five pillars represent the unity of the five branches of the United States military serving steadfast together.” Those include the US Marine Corps, the US Navy, the US Army, the US Air Force and the US States Coast guard. “They are staggered in size with their appropriate military seal placements on each pillar based upon the Department of Defense prescribed precedence.”

However, a huge attention was paid on the construction of this monument at the time. “Each year, the center of the sun is slightly offset from other years by just a few horizontal or vertical arc-seconds relative to the timing of the required azimuth/altitude position of the sun,” Jim Martin, the AVM chief engineer explained. “Using the statistical mean of the 100-year data, the altitude and azimuth angles for the structure were adjusted to provide time/error fluctuation of plus or minus 12 time seconds from the International Atomic Time mark of 11:11:11 a.m. <…> we also checked the variance 500 years out, and if the structure is still standing, it will work.”

Both the azimuth angles and the altitude were adjusted in order to provide time fluctuation of minus or plus 12 seconds. Statistical data of 100 years were used in this process.
