[time-nuts] Shortt Clock Recent Measurements

[Brooke Clarke]

Hi Tom:

The way I read the comment about detecting the influence of the Moon was that it was discovered in 1984, but I was under 
the impression that Loomis found it long before.
I looked on other Wiki pages and did not see on any of the them information about Loomis and the effect of the Moon on 
pendulum clocks.

Have Fun,

Brooke Clarke
