 OFFSET -1999,102 COMMENTS The moment of the 'greatest eclipse,' defined as when the axis of the moon's shadow cone is closest to Earth's center, is used for determining this sequence. Important Note: The dates and times in the data described below are in Terrestrial Dynamical Time (TD). Adjustment is required for Universal Time. Hybrid eclipses, which are total on some parts of their paths and annular on other parts, are NOT counted here. The 5000 sequence values in the b-file were derived from the NASA catalog (describing 11898 solar eclipses of all types, historical or predicted, during this time period, 2000 BCE to 3000 CE). There are 3173 total solar eclipses and 569 hybrid solar eclipses during this 5000-year period. LINKS Rick L.
