I've got a part-time job http://fittor.fun/butterflilove-kisses/ xxnmx "Though the eclipse will begin at 5:50 p.m. (first contact), this event cannot be seen. The moon is only then beginning to slip into the dim penumbral shadow. Besides, it will have just risen at 5:47 p.m. and will be close to the horizon. Only as the eclipse progresses will an observer see a slight darkening of the lunar surface as the Earth's penumbral shadow sweeps across it from south (bottom) to north (top). Mid-eclipse, or maximum, will occur at 7:50 p.m. when 76 percent of the lunar disk will be within the penumbral shadow. At that time an informed observer should notice the subtle shading of the southern portion of the moon. The northern 24 percent will remain unchanged.
