Last lunar eclipse on Sunday until 2018


Don’t miss this Sunday September 27 lunar eclipse because the next one won’t happen until 2018.

This year, it occurs during the Harvest Moon, which is the closest Full Moon to today's Autumn Equinox. The next time a lunar eclipse coincides with a Harvest Moon will be 2025. The Moon will also seem a little bigger than usual this year because it’s a supermoon.

The eclipse technically begins at 8:11 p.m. when the Full Moon touches Earth’s outer penumbral shadow. However, we won’t see anything until 9:07 p.m. when the umbral phase darkens the left edge of the Moon.

The best time to see the eclipse is during totality, which begins at 10:11 p.m. and lasts until 11:23 p.m. when Earth’s shadow darkness the entire lunar surface. It will look a deep red because of refracted sunlight from the Earth’s atmosphere.

You can see the lunar eclipse from almost everywhere near Applaby Line where there is a clear sky. From a dark location, as the moon darkens, the stars of the Milky Way will seem to pop into existence. It should be a good show. Look for my report on CHCH-TV.

Planet watching

Mercury is seen in the western evening twilight sky and Venus shines brightly in the eastern dawn sky. Mars is low in the eastern twilight morning sky, while Jupiter is also low in the eastern dawn sky. Saturn is low in the southwest mid-evening sky setting late evening.
