[net.space] Eclipse & phase of the moon

Vince@sri-unix (07/06/82)

Does anyone out there have algorithms for 
   a) Calculating times of eclipses
and
   b) Calculating relative totality at a point in time during the eclipse 
      (e.g. how much of the moon is visible, how much is visible due to 
      refraction, etc.)

I have a program here which calculates and displays the phase of the moon,
and a rather serious bug became evident starting at around 1:30 (EDT) this
morning....
