>> Preston Dyches: What's Up for November?
A lunar eclipse, the moon and planets,
and the Leonid meteors.
A total lunar eclipse is on the way
to provide a little celestial magic
early on the morning of November 8th.
The eclipse will be visible to viewers
in North America, the Pacific region,
Australia, and eastern Asia anywhere the moon
is above the horizon while the eclipse is happening.
For observers in the Eastern Time Zone
of the US and Canada, the partial eclipse
begins a little after four a.m.
It reaches full eclipse about 5:15 local time,
and the moon then sets while still in eclipse for you.
For observers on the west coast of North America,
that translates to the partial eclipse
beginning just after one a.m., and reaching
full eclipse by about 2:15 a.m.
You'll be able to see the entire eclipse
unfold before sunrise, weather permitting,
as the moon exits the dark part of Earth's shadow,
called the umbra, a few minutes before five a.m.
During a lunar eclipse, you'll likely notice
that you can see a lot more faint stars,
as the usually brilliant full moon dims to a dull red.
And during this eclipse, viewers with binoculars
can spy an extra treat.
The ice giant planet Uranus will be visible
just a finger's width away from the eclipsed moon.
Check your local details to find out
if the eclipse is visible from your area,

In the pre-dawn hours of November 11th,
you'll find the Moon directly between Mars
and the bright bluish star Elnath.
Elnath is the second brightest star
in the constellation Taurus, after reddish Aldebaran,
and it forms the northern horn of the bull.
You'll find that Elnath is about the same brightness
as the star Bellatrix in nearby Orion,
where it forms one of the hunter's shoulders.
On November 20th, in the hour before sunrise,
look to the southeast to find a slim crescent moon
hanging right above the bright bluish star Spica.
It's a giant star ten times the mass of our sun,
and 12,000 times more luminous.
Fortunately for us, it's located 260 light years away.
And in the evening sky on November 28th,
a beautiful crescent moon hangs beneath Saturn
in the south after sunset.

The Leonid meteor shower is active throughout November.
It peaks after midnight on the 18th,
with something like 15 to 20 meteors per hour
under clear, dark skies.
Now, the shower's name comes from
the constellation Leo, the lion,
from which its meteors appear to radiate.
The meteors are dusty bits of debris
left behind by Comet Tempel-Tuttle as it orbits the sun.
This comet was actually discovered twice independently.
On the peak night for the Leonids this year,
the moon will be about 35% full,
meaning it will interfere with your ability
to see the fainter meteors.
However, Leonid meteors are often bright,
with trails, also called trains,
that persist for a couple of seconds
after they streak across the sky.
And while the moon will be rising in the east
with Leo around midnight, it's actually better
to view the sky away from the meteors'
apparent point of origin, by lying back
and looking straight upward,
as any meteor trails you see will appear
longer and more spectacular.
