The National Research Institute of Astronomy and Geophysics is getting ready to monitor the total lunar eclipse that will occur in Egypt and other Arab countries tonight. Dr. Amir Hussein, research professor at the Institute, will be monitoring the eclipse by telescope and a very accurate camera. The phenomenon will occur tonight, beginning at 8:23 pm with a partial eclipse. The total lunar eclipse will start at 9:22pm and will continue until 11:03pm. A partial eclipse will return, until the eclipse ends at 12:03 am. The entire eclipse, with all of its phases, will last five hours and 36 minutes. This eclipse is considered unusual, as the total eclipse phase will last more than 100 minutes. During total eclipse, the moon will completely disappear from sight and will look very dark. In other lunar eclipses, the moon often looks dark red. The partial eclipse can be seen with the naked eye. Unlike a solar eclipse, which requires the use of special glasses to view safely, a lunar eclipse doesn't cause any harm to the eye.
