A penumbral lunar eclipse set to occur on August 6, 2009, will be the third of four lunar eclipses during the year. The eclipse is predicted to last for about three hours.
Will the Eclipse be Visible?
The August 6 eclipse will not be visible to the naked eye as its magnitude is only 0.402, according to NASA. There is little chance of seeing more than the slightest hint of this passage (Harrington, 1997). This lunar eclipse will bring the moon’s northern limb into earth’s penumbra.
When Will the Eclipse Occur?
The first penumbral contact occurs at 23:04:21 Universal Time (UT). The ecliptic conjunction occurs at about 00:54:52 UT and the point of greatest eclipse occurs at about 00:39:11 UT. The eclipse ends at about 02:14:08 UT.
Where Will the Eclipse Be?
The moon will be in the constellation Capricornus during the eclipse, which will be near the meridian at maximum for them. For what there will be to see, sky watchers in Europe and Africa will be best placed to see it (Harrington, 1997).
