![]() ![]() The eclipse occurs at the ascending node of Luna's orbit in southern Aquarius. It is a deeper event since it is the first central total eclipse since 2000. The second lunar eclipse of the year is another total eclipse. After one more partial eclipse, the series will produce its first total solar eclipse on 2043 Apr 09.Ĭlick for special web page on the Total Lunar Eclipse of 2007 Aug 28 Total Lunar Eclipse of August 28 This event is the 20th partial eclipse of Saros series 149. The Sun's altitude and azimuth, the eclipse magnitude and obscuration are all given at the instant of local maximum eclipse. Local circumstances for a number of cities within the zone of partial eclipse are given in Universal Time in Table 2. The penumbral contact times with Earth are listed below. Greatest eclipse takes place at 02:31:56 UT when the eclipse magnitude will reach 0.8754. The first solar eclipse of 2007 occurs at the Moon's ascending node in Pisces and is visible from eastern Asia and parts of northern Alaska ( Figure 2). The timing of craters is useful in determining the atmospheric enlargement of Earth's shadow (see Crater Timings During Lunar Eclipses). Table 1 lists predicted umbral immersion and emersion times for 20 well-defined lunar craters. From western North America, only the final penumbral phases are visible. Observers in eastern North and South America will find the Moon already partially or totality eclipsed at moonrise. Western Australia catches part of the initial partial phases but the Moon sets before totality. For example, the Moon sets while in total eclipse from central China and southeast Asia. In eastern Asia, moonset occurs during various stages of the eclipse. The entire event will be visible from Europe, Africa and western Asia. Saturn shines at magnitude +0.8 about 24º northwest of the Moon near the western border of Leo. Alphard or Alpha Hya (mv = +1.99) is 28º to the southwest and Procyon (mv = -0.05) is 50º to the west. Spica (mv = +0.98) is 40º southeast of the eclipsed Moon, while Arcturus (mv = -0.05) is 49º to the northeast. south).ĭuring totality, the spring constellations will be well placed for viewing so a number of bright stars can be used for magnitude comparisons. Note that it may also be necessary to assign different Danjon values to different portions of the Moon (i.e. 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 dramatically with time. Thus the northern sections of the Moon will appear much brighter than the southern part, which lies deeper in the shadow. In contrast, the Moon's northern limb will lie 6.9 arc-minutes from the northern edge of the umbra and 32.2 arc-minutes from the shadow centre. At this time, the umbral magnitude peaks at 1.2331 as the Moon's southern limb passes 2.4 arc-minutes north of the shadow's central axis. The Moon's path through Earth's shadows as well as a map illustrating worldwide visibility of the event are shown in Figure 1.Īt the instant of greatest eclipse (23:21 UT) the Moon will lie in the zenith for observers in Nigeria and Cameroon. The timings of the major phases of the eclipse are listed below. ![]() Although the eclipse is not central, the total phase still lasts 73 minutes. The Moon's orbital trajectory takes it through the northern half of Earth's umbral shadow. During the eclipse, the Moon is in southern Leo, about 13º east of the 1.3-magnitude star Regulus (alpha Leo). The eclipse occurs at the descending node, 3.2 days before apogee and 1.9 days after the Moon occults Saturn (northern and eastern Europe). The first of two total lunar eclipses in 2007 is unique in that it is partly visible from every continent around the world. Total Lunar Eclipse of 2007 Mar 03 Total Lunar Eclipse of March 03 To learn more about UT and how to convert UT to your own local time, see Time Zones and Universal Time. This astronomically derived time system is colloquially referred to as Greenwich Mean Time or GMT. Contact times for each principle 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 Time or UT. The lunar eclipse diagrams also include the path of the Moon through Earth's shadows. World maps show the regions of visibility for each eclipse. Predictions for the eclipses are summarized in Figures 1 through 4. Two central solar and two lunar eclipses occur in 2007 as follows: Published in Observer's Handbook 2007, Royal Astronomical Society of Canada ![]()
