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.... --vaf
