```Thanks to you Randy and Dale.

CONFESSION:    I am a dunce, but I do not see what you and Dale previously
sent about Great Circle Mapper.  Inserting MY coordinates and a given
distance only displays a circle of that given distance with me as the
center.  Everything outside that distance surely is not in the shadow zone.
Perhaps, I do not know what the magic distance should be?

Here is a link to a great circle mapper.  You can put in coordinates and
generate a world map with your location and concentric cirles at any desired
distance.  I have done mine for each 10 degrees out to the shadow zone and
then again from the far side of shadow zone.  I just set this image as
wallpaper for my desktop for quick reference.
