The Night Sky:
Rare 'supermoon' total eclipse will be Sept. 27
By GERRY LEBING
Perseids meteor shower on Aug. 12 was a good show. I saw
numerous shooting stars, but the best moment for me happened when two
very bright meteors simultaneously streaked across the sky side by side.
I spent several fruitless nights trying to get a good shot of the
Andromeda Galaxy, M31. Hopefully, I will be able to get a good
shot of it in the coming months.
Meanwhile, above is a shot of Messier 20, the Trifid Nebula, which is
about 5,000 light years away. It has a visual magnitude of
+6.3. The back sections that seem to divide the red
cloud are lanes of black dust.
SEPTEMBER SKY WATCHING
September starts with Neptune as close as it gets to the Earth.
You’ll need a telescope to view it. With a visual magnitude of
+7.8, you can’t see it with the naked eye. Neptune is 2.7 billion
miles away, so it’s not someplace you drive to for the weekend.
We see the light it reflects from the sun. That means the
light has traveled close to 5 ½ billion miles before we can catch a
glimpse of this blue planet.
Uranus is also visible for much of September. With a magnitude of
+5.7, it can be viewed on very clear nights. Because of city
lights, if you want to try viewing Uranus with the naked eye, you’ll
have a better chance of seeing it by taking a ride out to Ramp 27 or
some other dark area.
On Sept. 4, Mercury will be at its highest point above the evening
horizon. Look for it just above the southwest horizon right after
The Fall Equinox occurs on Sept. 23.
On Sept. 27, there will be a rare sky event -- a so-called
"supermoon" with a total lunar eclipse. September’s full moon, also
known as the Harvest Moon, is called a "supermoon" because it appears
significantly larger and brighter than usual.
A total eclipse of the moon starts at about 9 p.m. with the maximum
coverage of the moon happening about 10:47 p.m. According to NASA, it
will be the first supermoon eclipse since 1982, and the last until
The total lunar eclipse will be visible to observers throughout the
Americas, Europe, Africa, western Asia and the eastern Pacific Ocean.
Last Quarter: Sept. 5
New Moon: Sept. 13
First Quarter: Sept. 21
Full Moon: Sept. 27.
The Fall Equinox means the tilt of the earth towards the sun is close
to zero. So both the northern and southern hemispheres receive
the same amount of sunlight -- 12 hours. It signals the beginning
