![]() It is not possible to predict the exact brightness distribution in the umbra, so observers are encouraged to estimate the Danjon value at different times during totality (see Danjon Scale of Lunar Eclipse Brightness). ![]() Since the Moon samples a large range of umbral depths during totality, its appearance will change significantly with time. Thus, the northern half of the Moon will appear much darker than the southern half because it lies deeper in the umbra. In contrast, the Moon's southern limb lies 9.0 arc-minutes from the southern edge of the umbra and 40.0 arc-minutes from the shadow centre. The umbral eclipse magnitude peaks at 1.2907 as the Moon's northern limb passes 1.7 arc-minutes south of the shadow's central axis. ![]() The times of the major eclipse phases are listed below.Īt the instant of greatest eclipse (07:45:40 UT) the Moon lies at the zenith for a point in the South Pacific about 3000 km southwest of the Galapagos Islands. The Moon's path through Earth's shadows as well as a map illustrating worldwide visibility of the event are shown in Figure 1. The Moon's orbital trajectory takes it through the southern half of Earth's umbral shadow.Īlthough the eclipse is not central, the total phase still lasts 78 minutes. This is the first of four consecutive total lunar eclipses in 20 (see Lunar Eclipse Tetrads). The apparent diameter of the Moon is close to its average since the eclipse occurs nearly midway between apogee (April 08 at 14:53 UT) and perigee (April 23 at 00:28 UT). The eclipse occurs at the lunar orbit's ascending node in Virgo. The first eclipse of the year is well placed for observers throughout the Western Hemisphere.

The lunar eclipse diagrams also include the path of the Moon through Earth's shadows.Ĭontact times for each principal phase are tabulated along with the magnitudes and geocentric coordinates of the Sun and Moon at greatest eclipse.Īll times and dates used in this publication are in Universal World maps show the regions of visibility for each eclipse. ![]() Predictions for the eclipses are summarized in Figures In 2014, there are two solar eclipses and two total lunar eclipses as follows.
