Flags should be flown at half-staff until sunset Feb. 20, the day of Supreme Court Justice Antonin Scalia’s interment.
President Obama issued the order last week.
To fly the flag at half-staff, hoist the flag to the peak for an instant and then lower it to the half-staff position. The flag should be raised to the peak again before it’s lowered for the day.
For additional information, refer to the Postal Service’s guidelines on U.S. flag display and maintenance.
