August 26, 2007 - Disappearing Moon Welcome to the Nature Notebook. Early Tuesday morning, the Moon disappears, eaten away by Earth’s shadow in this year’s second lunar eclipse. Unfortunately for us easterners, the Moon will be setting in the west as it reaches totality, when its surface is completely in shadow. Because a lunar eclipse only happens during a full moon, the Sun will be rising in the east as the Moon slips below the western horizon. Daylight will break across the morning sky as the Moon disappears from view. Even so, this eclipse is worth a look if clear skies prevail. Watch for the first hints of the eclipse at about 4:30 a.m., August 28th. Totality occurs near 6 a.m. Even though we will not have the best view of this eclipse, next year on February 21st, we will be in position to see an entire lunar eclipse from Pennsylvania. This is PPL's naturalist, Jon Beam, with the Nature Notebook for WVIA.
