[Question whether high or low tides accompany a sunset eclipse.]

> if moon (in the east) it will be high tide
> if sun (in the west) it will be low tide

This question was somewhat underspecified.  Of course, in the best of
all possible worlds it would be a low tide -- two bulges of water (one
directly under the moon, one exactly opposite) are created as the
result of tidal forces.  This was all discussed weeks ago in this
newsgroup.  However, the tides at any one location can lead or lag the
theoretical time by several hours because of resonance effects in
oceans and large bays.  In practice, without a detailed understanding of
the tidal patterns at the location in question, you have very little
chance of getting an accurate answer.
