SUN IN THE 20TH CENTURY A.D.
We omit those eclipses which are visible only in polar regions or are of excessively short duration. The first column gives the date of the eclipse, the next the duration of totality, the third the node near which the eclipse occurs and the number of the Saros series to which it belongs, repeated eclipses having the same num ber. The last column states where the eclipse is visible.
