Another remarkable sky display will occur on Friday evening, October 18, with the 2013 Penumbral Lunar Eclipse. What the viewers can observe is the slight darkening of the Moon's lower part as it passes through the lighter shadow right after it has risen.

The experts stated in the Space.com report: "Earth's natural satellite will pass through our planet's faint outer shadow, known as the penumbra, on Friday, with the time of deepest eclipse occurring at 7:50 p.m. EDT (2350 GMT). The effect of such a penumbral eclipse will be subtle compared to the dramatic spectacle of a total lunar eclipse, but it's still worth craning your neck skyward."

According to Alan MacRobert of Sky and Telescope, the unusual shading on the lower part of the Moon "should be fairly plain." Mr MacRobert noted on his report that viewers will be able to notice lesser traces of the penumbral shading for approximately 45 minutes before and after the mid-eclipse if they looked for the penumbral shadow "moving from east to west across the disc."

Without any weather or cloud disturbances, the viewers in North and South America will experience the maximum eclipse around the time of the moonrise, which is also the time of sunset. The Discovery.com report on where to best view the 2013 Penumbral Lunar Eclipse reads: "The farther east and north you are located, the better your chances of seeing this eclipse."

The 2013 Penumbral Lunar Eclipse will be visible as well throughout the Caribbean, Europe, Africa and Asia. The Discovery report further reads: "For observers in Africa, Europe, and western Asia, the eclipse will occur in the middle of the night when the moon is high overhead. The partial shading will be visible as the slight reddish dimming of the normally bright full moon."

Viewers who are interested to experience the October 18 penumbral lunar eclipse can head to the Starlight Astronomy Club where a public sky watch at the Canoe Creek State Park will be available from 6 p.m. until 9 p.m. Another lunar eclipse will take place in the later part of the week in case viewers missed the Friday lunar eclipse while the next total lunar eclipse will take place on April 14, 2014.
