Meeting update, Decoupling Civil Timekeeping from Earth Rotation

[Rob Seaman]

Howdy,

Just working my way through the list of invitees to the UTC meeting with the appended update.  Apologies if you see this several times.  There will be impacts on virtual observatories as well as actual observatories.

Thanks!

Rob

The Exton workshop will be the last chance to influence the decision while starting to plan for the Y2K-like fallout.  The International Earth Rotation Service has circulated the announcement:

> The program is shaping up nicely and will be released in a few weeks.  There will be a range of submissions from institutions such as the IAU, IERS and USNO as well as speakers from observatories as diverse as the Large Binocular Telescope, the Vatican and various astronautics projects.  And there will be a grab bag of other topics ranging from sundials and solar eclipses to celestial navigation and the 10,000 year clock.  We have just added another sponsor in the American Institute of Aeronautics and Astronautics.

> On the day following the meeting (10/7) there will be a talk by Ken Seidelmann (former director of astrometry at USNO) and tour of the analemmatic sundial at Longwood Gardens (http://bit.ly/omBqrE).  Ken provided its accurate calibration; the ITU's redefinition of Coordinated Universal Time would render calibration rather a moot issue for this and all sundials.
