The Rings Of Saturn,
As Seen
From Earth
The rings of Saturn are never visible as a complete circle surrounding Saturn. This would be a view from space somewhere over Saturn's north pole, or south pole.
Sometimes the rings of Saturn are visible from some point slightly north of Saturn's equator.
As our position relative to the rings of Saturn changes, there comes a time at which we cannot see them. The rings of Saturn are very thin.
Then for a time the rings of Saturn are visible from points in space south of Saturn's equator.
The most complete possible views of the rings of Saturn would come at some time in between the disappearances of the rings from our view.
Now is a time for all competent astrologers who are also scholarly historians to sort out the differences in human experience while the rings of Saturn are visible looking southward at them, as different from human experience while the rings of Saturn are visible looking northward, toward Saturn's north pole.
In theory, we should experience some cultural changes during the times at which the rings of Saturn are invisible.
Here is the Ephemeris of the Rings of Saturn computed by Richard E. Schmidt, U.S. Naval Observatory, with his comments on how to read it. Dr. Schmidt offers no word of any possible astrological influence from the rings of Saturn, in any perspective. Reference: Sky & Telescope, December 1979.

Ephemeris of the
Rings of Saturn
Richard E. Schmidt RING DISAPPEARENCES
The accompanying table presents the times of all passages of the earth and sun through the plane of Saturn's rings be teen the years 1600 and 2250. It thus includes all of these events since the invention of the telescope. They have been calculated by the author from G. Struve's elements of the ring plane and the JPL DE-102 coordinates of the planets.
In the table, the first column gives the date, with the Ephemeris time expressed as a decimal fraction of a day. (For ordinary purposes, this may be regarded as Universal or Greenwichtime.) The next two columns tell whether it is the earth or the sun that is passing through the ring plane, and whether it is passing northward (N) or southward (S). The last two columns give the heliocentric longitudes of the earth and Saturn. When these two longitudes are equal, Saturn is at opposition; if they differ by 180�, Saturn is in conjunction with the sun.
As inspection of the table shows, for each crossing of the ring plane by the sun there are either one or three by the earth. When there is a single crossing, it is during an unfavorable observing period, Saturn being near conjunction with the sun. Triple crossings by the earth afford at least one near Saturn's opposition.
The listed times may be in error by several hours. For example, a recent analysis of A. Dollfus' photographs of the edgewise rings in 1966 yielded a difference of more than nine hours between observa tion and prediction.
