Monthly Reports

Times stated in the following 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.


 The following 4-page monthly reports are in PDF format which requires Acrobat Reader. (Link at bottom of this page.)

Classification and co-ordinate files are at the bottom of this page, and are labelled "gdcc[year]-[month]".

Monthly files (1994 - 2006) are available from http://gdsoarchive.webs.com/.

Monthly files (2007 onwards)  that are not listed below, are available from http://gdsoarchive2.webs.com/.
