In the USA, the eclipse will already be underway when the moon rises on Saturday evening. Observing tip: Find a place with a clear view of the eastern horizon and station yourself there at sunset. As the sun goes down behind you, a red moon will rise before your eyes. Viewers guide.
The first of two total lunar eclipses in 2007 is unique in that it is partly visible from every continent around the world. 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). During the eclipse, the Moon is in southern Leo, about 13º east of the 1.3-magnitude star Regulus (alpha Leo). The Moon's orbital trajectory takes it through the northern half of Earth's umbral shadow. Although the eclipse is not central, the total phase still lasts 73 minutes. The timings of the major phases of the eclipse are listed below.
