Watching the Leonid meteor shower 2012

November 17, 2012

Faithful stargazers may already have spotted a few shooting stars from this year’s Leonid shower.  Best estimates are that the peak will come the night of Saturday, November 17.

Ready?

One of our best sources on viewing meteors is the StarDate website.  Their advice for tonight:

The next meteor shower is the Leonids on the night of November 17

The best viewing for this year’s Leonid meteor shower will be several hours before dawn on November 17. The shower should produce perhaps a dozen or so “shooting stars” per hour. The best view comes in the wee hours of the morning, as your part of Earth turns most directly into the meteor stream.

What is a meteor shower?

A meteor shower is a spike in the number of meteors or “shooting stars” that streak through the night sky.

Most meteor showers are spawned by comets. As a comet orbits the Sun it sheds an icy, dusty debris stream along its orbit. If Earth travels through this stream, we will see a meteor shower. Although the meteors can appear anywhere in the sky, if you trace their paths, the meteors in each shower appear to “rain” into the sky from the same region.

Meteor showers are named for the constellation that coincides with this region in the sky, a spot known as the radiant. For instance, the radiant for the Leonid meteor shower is in the constellation Leo. The Perseid meteor shower is so named because meteors appear to fall from a point in the constellation Perseus.

What are shooting stars?

“Shooting stars” and “falling stars” are both names that describe meteors — streaks of light across the night sky caused by small bits of interplanetary rock and debris called meteoroids vaporizing high in Earth’s upper atmosphere. Traveling at tens of thousands of miles an hour, meteoroids quickly ignite from the searing friction with the atmosphere, 30 to 80 miles above the ground. Almost all are destroyed in this process; the rare few that survive and hit the ground are known as meteorites.

When a meteor appears, it seems to “shoot” quickly across the sky, and its small size and intense brightness might make you think it is a star. If you’re lucky enough to spot a meteorite (a meteor that makes it all the way to the ground), and see where it hits, it’s easy to think you just saw a star “fall.”

How can I best view a meteor shower?

Get away from the glow of city lights and toward the constellation from which the meteors will appear to radiate.

For example, drive north to view the Leonids. Driving south may lead you to darker skies, but the glow will dominate the northern horizon, where Leo rises. Perseid meteors will appear to “rain” into the atmosphere from the constellation Perseus, which rises in the northeast around 11 p.m. in mid-August.

After you’ve escaped the city glow, find a dark, secluded spot where oncoming car headlights will not periodically ruin your sensitive night vision. Look for state or city parks or other safe, dark sites.

Once you have settled at your observing spot, lie back or position yourself so the horizon appears at the edge of your peripheral vision, with the stars and sky filling your field of view. Meteors will instantly grab your attention as they streak by.

How do I know the sky is dark enough to see meteors?

If you can see each star of the Little Dipper, your eyes have “dark adapted,” and your chosen site is probably dark enough. Under these conditions, you will see plenty of meteors.

What should I pack for meteor watching?

Treat meteor watching like you would the 4th of July fireworks. Pack comfortable chairs, bug spray, food and drinks, blankets, plus a red-filtered flashlight for reading maps and charts without ruining your night vision. Binoculars are not necessary. Your eyes will do just fine.

StarDate offers a wealth of resources on meteor showers, and clips from their radio programming on specific events.

Here’s a map of where to look in the sky (also from StarDate, though that’s not where I found it!):

I haven’t seen anything this year (but I’ve not left the city,either).

1833 Leonid shower, from 7th Day Adventist book- Wikimedia

Wikipedia describes this old woodcut: "The most famous depiction of the 1833 actually produced in 1889 for the Adventist book Bible Readings for the Home Circle - the engraving is by Adolf Vollmy based upon an original painting by the Swiss artist Karl Jauslin, that is in turn based on a first-person account of the 1833 storm by a minister, Joseph Harvey Waggoner on his way from Florida to New Orleans."

There are a few spectacular shots of the Leonid meteors this year — got one you want to share?

Peak night was supposed to be November 17 Astronomy Magazine’s website holds out some hope that you might catch a few shooting stars on November 18.  It’s worth a look, if you’ve got skies.

Next up:  Geminids, with a peak night of December 13, 2011.


Leonid meteor shower 2010: Moon, Jupiter, and Leonids

November 17, 2010

Some stellar fireworks will be visible in your skies tonight, November 17, 2010.

The Moon is in conjunction with Jupiter.  The Leonid Meteor Shower will peak soon after the Moon and Jupiter set.

Oh, to be in the desert tonight, far away from the lights of the city!

Even in a city, the Moon and Jupiter should be clear, and near spectacular.

Things are great, if you’re looking up.

Leonid meteor scattered showers

Meteors from the Leonid shower could have been good viewing — generally, as I predicted, it was not spectacular.  At least BBC said so.

But if you can make the time, it’s almost always profitable — psychologically and spiritually — to look up at the sky.

Some who did look up got great photographs of the not-spectacular views.

If this isn’t spectacular, can you imagine what would be?
