OMSI will host the second of two lunar eclipse viewings in 2015 on Sunday evening, September 27. That evening the full moon will slide through the dark shadow of the Earth and for 72 minutes the only light hitting the Full Harvest Moon will be a reddish glow from all of Earth’s sunrises and sunsets resulting in a total lunar eclipse. Weather permitting; a free viewing of the eclipse will begin at 6:30PM at OMSI South Parking. The Rose City Astronomers, and OMSI will have telescopes set up for attendees to use. OMSI Space Science Director, Jim Todd, will be presenting informal talks about the lunar eclipse and the autumn night sky.
Unlike solar eclipses in which the Sun's rays can damage the eyes, lunar eclipses are safe to watch with the naked eye. Lunar eclipses are unique in that no one can predict what color the Moon will turn during totality. Binoculars and telescopes will enhance the view.
The moon will rise at 6:55PM. from the east, with the sun setting at 6:59PM. in the west. We will see most of the moon within the dark umbra of Earth as it rises. The totality begins at 7:11PM with the point of the greatest eclipse occurring at 7:47PM. The eclipse’s total phase will last for 72 minutes. The Moon will be just 8 degrees above the eastern horizon at the instant of the greatest eclipse. Finally, the partial eclipse ends at 9:27PM.
This will also be the largest full moon of 2015, as it will also be at perigee on September 27 at 5:46PM, at a distance of 221,753 miles from Earth.
