%N The number of total solar eclipses visible from Earth's surface during year n (TD).

%C 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.

%C Important Note: The dates and times in the data described below are in Terrestrial Dynamical Time (TD). Adjustment is required for Universal Time.

%C Hybrid eclipses, which are total on some parts of their paths and annular on other parts, are NOT counted here.

%C 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).

%C There are 3173 total solar eclipses and 569 hybrid solar eclipses during this 5000-year period.
