calculate the rotation rate for one epoch
5:27 A.M. HUb' looking for the
"rate of change" for the number
of
for example Parigee's of the Moon
for each lunar month
New moon to new moon
expressed only in Lunar units
{forget Years, Months, days, hours, etc}
Just use Lunar orbital data vs Perigee[or?] Lunar data

You have to be careful, here. The time from perigee to perigee is not necessarily the same as the time from new moon to new moon.

Ain't that a fact -- if it were, we wouldn't have "annular" solar eclipses and "total" solar eclipses . . .

Speaking of which, everybody hoping for clear skies next Friday?

Also, anybody else already to the point where they can't wait for Aug 21, 2017? /phpBB/images/smiles/icon_wink.gif
