Riyadh, Dhu-AlHijjah 13, 1436, Sep 27, 2015, SPA -- The moon of the month of Zul-Hijja will totally disappear before it sets on the western horizon at the dawn of Monday, tomorrow, due to the complete eclipse which will cause the disappearance of the light of the moon when it passes behind the earth's shadow and changes position to become with the earth and sun on a straight line, astronomers said today. In a statement to SPA, the astronomer researcher of the Astronomy and Space Department at King Abdulaziz University Mulhem bin Mohammed Hindi said that the eclipse will start at 4:07 a.m., on Monday, according to Saudi Arabia's local time, and reaches its climax at 5:47 a.m. and lasts for three hours and a half. The Kingdom's residents could see its first phases before the moon sinks and the sun rises, noting that the longest period of the eclipse will be seen in the western regions of the Kingdom and lessens as long as one moves eastwards. Hindi drew the attention that the eclipse will be monitored in all Arab African countries, Europe, and east of the United States. --SPA 18:04 LOCAL TIME 15:04 GMT www.spa.gov.sa/w
