[LEAPSECS] USNO predictions of UT1-UTC

[Seaman, Robert Lewis - (rseaman)]

Isn’t the question whether those responsible for issuing leap seconds will follow through and trigger a negative leap second even if Bulletin A says it’s time? Much consternation will be feigned.

The USNO predictions in IERS Bulletin A have been pretty good...

It will be interesting to see what kind of consternation arises
if the predictions start saying the negative leap is impending.

Somewhere in USNO/UKHO somebody has been making longer term
predictions for use in the navigational almanacs, but as far
as I know those have never been published.
