On Sunday Evening Jan 20, 2019 the Full Moon will pass through the Earth's Shadow producing a Total Lunar Eclipse. You don't need any special equipment or dark skies to view this eclipse. Just go out and look for the moon. Binoculars or a small telescope will enhance the view but are not necessary to see the moon.The Full Moon will rise in the ENE near sunset but by 9:15 or so you may notice that it appears a bit shaded on the left. This shading is called the PENUMBRA when the Earth blocks part of the Sun's light.The PARTIAL ECLIPSE begins at 9:34 PM as the moon will begins to enter the Earth's inner shadow called the UMBRA. Look for a curved "bite" on the Left side of the moon. As the moon slips into the Umbra more and more will be covered.The TOTAL ECLIPSE phase begins at 10:41 PM. The moon will be fully covered by the Earth's shadow. The moon will be much dimmer and may look a dull orange or reddish to brown color. The color is caused by the earth's atmosphere bending light around its edge onto the moon. You'll be looking at the combined effect of all the sunrises and sunsets along the earth's edge!The moon will be the dimmest at the mid-point of the eclipse at 11:12 PM. The total eclipse will end at 11:43 PM when the moon finally emerges from the umbra. It will take another hour for the moon to reverse the partial eclipse phase when it finally leaves the edge of earth's shadow at 12:51 AM on Jan 21.More details of the eclipse can be found in our January 2019 newsletter.
