As stated. "YOU DO NOT WORK FOR TRUMP. You supposedly love America and work to Protect and Serve the public. That's US.. the people. Please help us maintain our beautiful country. Thank you
Local sheriffs and chiefs of police across the state in all states can help stop this madness.

Maintain the peace, arrest those destroying property, and control the situation.

BUT do not allow the dictator Trump to push you to ignore your oath to the people you serve. You do not work for Trump.

A tour is possible if you know somebody there or it’s an official visit. USNO hasn’t given public tours in some time.

Other plates showed the planet as a tiny, round dot. Christy examined a number of Pluto images from the USNO archives, and he noticed the elongations again. Furthermore, the elongations appeared to shift relative to the stars over time.

I continue to find it hilarious that the dipshits in comms at the White House don't know that we're in Daylight Time now and for 2/3 of the year. Perhaps they should ask the USNO for a primer.
Ahh president sitting for a press interview with former ruling party chair and daughter-in-law

That USNO time announcement has been the same voice for almost 50 years!

On 22 June 1978, an astronomer at the U.S. Naval Observatory in Washington, D.C. was making routine measurements of photographic plates taken with the 1.55-meter (61-inch) Kaj Strand Astrometric Reflector at the USNO Flagstaff Station in Arizona.

if anyone at NIST or USNO is reading this I would like to suggest Dick Clark's New Year's Rockin' Time Dot Gov would be an outreach opportunity on par with the NORAD Santa Tracker

Isabel Martin Lewis was born #OTD in 1881. The first woman to be hired by the USNO as an assistant astronomer, she worked on eclipses. She held regular columns in several magazines to popularize science and astronomy.

The clocks can be repaired and recalibrated using the U.S. Naval Observatory clocks, with European clocks as a backup.

There's plenty of redundancy in the system and, as a note, GPS is calibrated from the USNO, not NIST.
