For comparison, here is the last previous grand cross involving the same planets.
This one was more precise, but it is important to remember that it is really
the T-cross involving Saturn, Uranus, and Pluto which is the most critical part
of the configuration and that this lasts for many years. In the case of the
depression in the 1930's this was already well in place several years earlier,
and in the early part of the next millenia it will come in around 2008.
