Visibility of the Total Lunar Eclipse of August 28, 2007
August's lunar eclipse is well-placed for North and South America as well as the Pacific, eastern Asia and Australia. All of North America will witness some portion of the eclipse, but western observers are favored. The early umbral phases will be in progress at moonset for observers in Maritime Canada. From the eastern USA, the Great Lakes region and Ontario, the Moon sets in total eclipse. Only observers to the west of the Rockies (including Alaska) will be treated to the entire event. All phases of the eclipse are also visible from islands of the Pacific Ocean, New Zealand and eastern Australia. Various stages of the eclipse are in progress at moonrise for eastern Asia. No eclipse is visible from Europe, Africa and western Asia.
Preceeding and following the eclipse are hour-long penumbral phases but these are faint and quite difficult to see. The more interesting and photogenic partial and total phases always take center stage to the penumbral phases. |
