TT = TAI + 32.184 seconds DUT1= (UT1-UTC) transmitted with time signals = 0.0 seconds beginning 09 April 2026 at 0000 UTC = -0.1 seconds beginning 29 October 2026 at 0000 UTC Beginning 1 January 2017: TAI-UTC = 37.000 000 seconds *********************************************************************** * ANNOUNCEMENTS: * * * * ------------------------------------------------------------------- * * Starting with the weekly Bulletin A products published on 15 * * October 2026, the daily and weekly products from the IERS Rapid * * Service/Prediction Centre will be computed using a new algorithm * * along with improved pre-processing of Atmospheric Angular Momentum * * inputs. The new algorithm is a Kalman smoother and weighted cubic * * spline. Going forward, users should expect to see improvements in * * the 0-7 day predictions of UT1-UTC from the current day of * * computation, with polar motion and celestial pole offset values * * remaining mostly unchanged. After implementation, slight changes * * may result if comparing to previous daily and weekly published * * values up to one year in the past of the date of this change. It * * is expected that these values are less than 0.05 mas in polar * * motion and 20 us in UT1-UTC. * * ------------------------------------------------------------------- * * * * There will NOT be a leap second introduced in UTC * * at the end of December 2026. * * * * The primary source for IERS Rapid Service/Prediction Center (RS/PC) * * data products is the official IERS RS/PC website: * * https://maia.usno.navy.mil * * * * IERS RS/PC products are also available from: * * NASA CDDIS: https://cddis.nasa.gov/archive/products/iers/ * * NASA CDDIS: ftps://gdc.cddis.eosdis.nasa.gov/products/iers/ * * IERS Central Bureau: https://datacenter.iers.org/eop.php * * * * Questions about IERS RS/PC products can be emailed to: * * eopcp@us.navy.mil * * * * Distribution statement A: * * Approved for public release: distribution unlimited. * * * *********************************************************************** ________________________________________________________________________ The contributed observations used in the preparation of this Bulletin are available at .
