MJD = Julian Date - 2 400 000.5 days
UT2-UT1 = 0.022 sin(2*pi*T) - 0.012 cos(2*pi*T)
- 0.006 sin(4*pi*T) + 0.007 cos(4*pi*T)
where pi = 3.14159265... and T is the date in Besselian years.
TT = TAI + 32.184 seconds
DUT1= (UT1-UTC) transmitted with time signals
= -0.2 seconds beginning 02 May 2019 at 0000 UTC
Beginning 1 January 2017:
TAI-UTC = 37.000 000 seconds

* Notice of Publication Web and FTP Shutdown: *
* The US Naval Observatory's Rapid Service/Prediction Center web and *
* FTP sites (at maia.usno.navy.mil and toshi.nofs.navy.mil) must *
* undergo modernization and have been offline since 24 October 2019. *
* The expected completion of work and return of service is estimated *
* as 30 April 2020. Please visit https://www.usno.navy.mil and submit *
* a Requirements Form to the USNO Public Affairs Official (PAO) if *
* the information you are seeking is not accessible via another *
* means. If the Requirements Form is not available, please directly *
* contact the USNO PAO Geoff Chester at email address *
* geoff.chester@navy.mil or phone number 202 762 1438. *
* *
* This shutdown has lead to the indefinite cessation of IERS *
* Bulletin A distribution emails. If this occurs, current *
* subscribers to the Bulletin A email distribution list may receive *
* future mailings from a different address (if this service is *
* restored). In the meantime, we will be unable to process email *
* subscription/unsubscription requests. *
* *
* Currently, updated EOPs may be available at NASA's Archive of *
* Space Geodesy Data anonymous FTP server at: *
* ftp://cddis.gsfc.nasa.gov/pub/products/iers *
* Daily EOP data may be uploaded here by 18:00 UTC, and *
* Bulletin A EOP data may be available by 20:00 UTC. *

The contributed observations used in the preparation of this Bulletin
are available at <http://www.usno.navy.mil/USNO/earth-orientation/
eo-info/general/input-data>. The contributed analysis results are based
on data from Very Long Baseline Interferometry (VLBI), Satellite Laser
Ranging (SLR), the Global Positioning System (GPS) satellites, Lunar
Laser Ranging (LLR), and meteorological predictions of variations in
Atmospheric Angular Momentum (AAM).

PREDICTIONS:
The following formulas will not reproduce the predictions given below,
but may be used to extend the predictions beyond the end of this table.
x = 0.1324 + 0.0548 cos A - 0.1053 sin A - 0.0257 cos C + 0.0184 sin C
y = 0.3562 - 0.0956 cos A - 0.0505 sin A + 0.0184 cos C + 0.0257 sin C
UT1-UTC = -0.1548 - 0.00044 (MJD - 58802) - (UT2-UT1)
where A = 2*pi*(MJD-58794)/365.25 and C = 2*pi*(MJD-58794)/435.
TAI-UTC(MJD 58795) = 37.0
The accuracy may be estimated from the expressions:
S x,y = 0.00068 (MJD-58794)**0.80 S t = 0.00025 (MJD-58794)**0.75
