max(UT) | time of maximum eclipse on Earth (universal time) |
hem |
gives an indication on the hemisphere where the eclipse was seen N = the axis of the Moon's shadow passes north of the Earth's centre S = the axis of the Moon's shadow passes south of the Earth's centre |
type eclipse | type of solar eclipse at maximum. The following types are indicated: central total: At some moment and viewed from some place on Earth the centres of Sun and Moon coincided and the Sun was completely obscured by the Moon. central annular: At some moment and viewed from some place on Earth the centres of Sun and Moon coincided but the Sun was not completely obscured by the Moon, leaving a brilliant 'ring' around the dark Moondisk. central total-annular: At some moment and viewed from some place on Earth the centres of Sun and Moon coincided but due to the varying distances between the Earth, the Moon and the Sun, the eclipse was at some times total and at others annular. non central eclipse (total or annular): At no instant did the line joining the centres of Sun and Moon coincide with a place on Earth, although the Sun was, at some place on Earth, either completely obscured by the Moon (total eclipse) or the complete surface of the moon passed before the Sun leaving a brilliant 'ring' around the dark Moondisk. (annular eclipse). partial eclipses: At no instant and nowhere on Earth there was a total or annular eclipse, but the Moon obscured the Sun partially. Our list indicates the maximum magnitude (decimal fraction) of these partial eclipses on Earth (1.000 = total, .000 = less than 0.05% obscured). |
