By presidential proclamation, flags are to fly at half-staff Friday as a mark of respect for the memory of Neil Armstrong.
That's the day of a private service for Armstrong, the first man to walk on the moon, who died last Saturday in Ohio at age 82.
There is also a rare 'blue moon' on Friday, a fitting wink to Neil Armstrong by the cosmic calendar. A blue moon occurs when there's a second full moon in one calendar month. It won't happen again until July 2015. The full moon cycle is 29.5 days so a blue moon is uncommon and has come to mean something rare. The moon actually won't be colored blue.
Armstrong's family has suggested paying tribute to him by looking at the moon and giving the astronaut a wink.
Flags are to be flown at half-staff at the White House and upon all public buildings and grounds, at all military posts and naval stations, and on all naval vessels of the Federal Government in the District of Columbia and throughout the United States and its Territories and possessions until sunset on such day.
For flags that can't be lowered, such as those on many homes, the American Legion advises that attaching a black ribbon or streamer to the top of the flag is an acceptable alternative. The ribbon should be the same width as a stripe on the flag and the same length as the flag.
For a wall mounted flag, three black mourning bows should be attached to the top edge of the flag, one at each corner and one in the center.
The U. S. Flag is to be flown at half-staff from sunrise to sunset Friday.
Also, one of four annual half-staff days is upcoming on Sept. 11, deemed Patriot Day. The other scheduled half-staff days include Peace Officer's Memorial Day (May 15), Memorial Day and Pearl Harbor Remembrance Day.
