GDSO Archive

                            E-MAIL:  gdso@earthling.net    or  gdso@value.net.nz

     This site, as the name suggests, holds old (but not out-of-date) solar data from 1994.

     More up-to-date data are on our other websites  http://gdsoarchive2.webs.com  or  http://gdso.webs.com/


      Times stated in GDSO documents are in Universal Time (UT), an approximation of all Universal Times, including Co-ordinated Universal Time / Temps Universel Coordonné (UTC).

PLEASE NOTE: There is NO other word order in English whatsoever, and NO other letter order (at all) for the name, and abbreviation, of Co-ordinated Universal Time (UTC). It is, after all, the co-ordinated version of Universal Time.

The language-independent abbreviation UTC, is meant to be used in all languages.

 


 LEAP SECOND. 

 

A leap second will be ADDED on 2016 December 31 at 23h 59m 60s UTC.

 This adjustment will be made to ensure that Co-ordinated Universal Time (UTC) [atomic time] does not deviate from UT1 (‘mean time’ on the Greenwich meridian) by more than 0.9 seconds in absolute value. The sequence of markers will be 23:59:59 ,  23:59:60 , 00:00:00. Time-signals that are usually six-pip, will be seven-pip signals.

 The last leap second was at the end of June 2015 [UTC].

 This decision was made by the International Earth Rotation and Reference Systems Service (IERS).

 

The vote on the future of leap seconds has been deferred 'til 2023.

PROJECT ARCHIVE.

'Project Archive' is an attempt to publish all GDSO monthly (observed, corrected and smoothed) results from 1973 onwards.

These will be in index-by-index format in PDF. Generally, these files will be 20 pages or less.

From the latter half of November 2011, these will become available from this website, and will appear below. Generally they will be updated every year around October or November.
