Stan,

Or very careful and slow reading...
I suppose that help is also easily avalable: in Bowditch and such books.
And on the NavList, of course:-)

No reasons for this, just ask:-)

You can ALWAYS apply it: but for 0 min it is just zero for Sun and Aries.

> For 0 minutes and 1 second?

Also zero for Sun and Aries, but you need the 1 sec correction.
The simple practical recipe: always apply it, instead of thinking
abut this every time.

I suppose everything is clear now about Aries (that is for fixed
stars)
and Sun now.

For planets it is a different matter, planets do not move uniformly,
and especially the Moon. GHA on the daily page for planets and Moon,
is not given exactly for x hour, 0 min, 0 sec, v and/or d correction
may be needed even in this case.
The reason is that they wanted most compact tables,
and did not want separate correction tables for planets and Moon.
Sun and Aries move almost uniformly, but the planets and Moon do not.
To make the same correction table serve all of them, they needed some
tricks.

In general, the Moon business is much more complicated than everything
else. Moon can be discussed separately.

But the Almanac is made in such a way, that you make no mistake by
following the same procedure independently of whether your minutes and
seconds are 0 or not.

Alex.
