[time-nuts] nuts about position

[Bob kb8tq]

Hi

Keep in mind when you look at the “peak to peak” numbers for solid tides that you may
have to observe things for 20,000 years to see the full peak to peak…… They also are
variable depending on just how close you are to what sort of coastline. ( = they interact
with sea tides when you get close).
