Here is a note from a 1963 book I have on the Moon. Interesting how flat earth and Internet teaching today changes everything
Details about penumbra, umbra, antumbra are not given, just plain language.
"An eclipse of the sun takes place during the new moon when the moon is between the earth and the sun. The shadow cast by the moon varies in length from 228,000 miles to 236,000 miles. For this reason, most of the times when the moon is in the right position for a solar eclipse, the moon's shadow does not reach the earth. On the other hand, when new moon occurs during perigee (when the moon is at the lowest point in its orbit), the moon's shadow extends several thousand miles beyond the earth. On such occasions, the shadow cast by the moon onto earth may cover an area of some 475 sq. miles." The How and Why Wonder Book of the Moon, THE MOON, page 17, 1963 Wonder Books, Inc.
Q:What happened between 1963 and now?
