Subject: Terminator


I have a site on my browser,   www.mapmaker.com/shadowfacts/sunweb.asp  
  that shows the terminator throughout the year.  It is fascinating to 
see how rapidly the shape changes, and I was astonished to see this 
evening that it is nearly a straight line, as we approach the equinox.

Of course, a little thought shows that I have should have expected 
this, but to see it on a 'flat earth' reminds one of what is happening 
to a globe, or the earth itself.

I expect others have more fun with other representations!

Doug
