The 11:33 UTC &#8220;during eclipse&#8221; Day\/Night Band image appears somewhat dim and washed out, due to limited illumination by only red sunlight being refracted by the Earth&#8217;s atmosphere into the eclipse shadow. Less than 2 hours later, the 13:14 UTC Day\/Night Band image appears much more bright with crisp cloud feature details, due to an abundance of illumination from the Full Moon.<\/p>\n<p>A few hours after sunrise in North America, a portion of the Moon was captured on the GOES-13<em> (GOES-East)<\/em> 0.63 \u00b5m visible channel image at 16:30 UTC <em><strong>(below)<\/strong><\/em>. Note how the edges of the Moon appear slightly jagged, caused by the fact that it was moving<em> (setting)<\/em> behind the Earth as the GOES-13 imager instrument was scanning horizontally step-wise from north to south. In addition, at the point where the edge of the Moon meets the edge of the Earth, there is a &#8220;lensing effect&#8221; where the Earth&#8217;s atmosphere is refracting light from the Moon and creating the illusion of a curved wedge of dark space that is visible within the atmosphere.<\/p>\n<p><a href=\"https:\/\/cimss.ssec.wisc.edu\/satellite-blog\/wp-content\/uploads\/sites\/5\/2014\/10\/141008_1630Z_GOES13_VISIBLE_MOON.GIF\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/cimss.ssec.wisc.edu\/satellite-blog\/wp-content\/uploads\/sites\/5\/2014\/10\/141008_1630Z_GOES13_VISIBLE_MOON.GIF\" alt=\"\" width=\"480\" height=\"360\" \/><\/a><\/p>\n<p>Speaking of sunrise, an interesting aspect of this lunar eclipse was that it was a rare &#8220;selenelion&#8221;, when the rising sun in the east could be seen at the same time as the non-eclipsed portion of the setting moon in the west (<a title=\"Space.com article on the Blood Moon lunar eclipse\" href=\"http:\/\/www.space.com\/27338-total-lunar-eclipse-rare-sunrise-selenelion.html\"><strong>Space.com article<\/strong><\/a>).
