Goodness, Gracious, Great Ball Of Fire!


It measured between 0.5 kiloton and 1.0 kilotons, it lit up the Utah sky, it landed some where in the Western Utah Desert. And it happened on Tuesday Night. It was the Great Utah Ball of Fire!

A fast-moving meteor lit up the night skies over most of Utah just after midnight Wednesday. Moments later, the phones lit up at KSL as people across the state called to tell us what they saw and ask what it was.

Scientists are calling it a "remarkable midnight fireball." The source of all the excitement was basically a rock, falling from space.

In addition to KSL, witnesses to the meteor quickly began call 911.

"I'm currently driving, but I just saw a giant blue flash in the sky, and it came down into the city," a caller from Ogden said.

A caller in Bountiful told dispatchers, "It flashed from the west, and it lit up the whole freakin' neighborhood."

A Salt Lake City caller said, "Ma'am, I'm not kidding you. I am terrified."

Professor David Kieda is chair of the University of Utah's astronomy department. He said the energy of the meteor coming into Earth's atmosphere was so powerful it has to be measured in Terawatts.

"It's almost like the consumption of the United States all at once. It was a fraction of a second," Kieda said.

When a meteor enters the atmosphere, it gives off a lot of heat and light. Folks at the Clark Planetarium say this rock was big--between the size of a microwave and washer-dryer unit.

Meteor Streak Lights Up the Night Across the State of Utah




20 years ago the people would have panicked thinking the bright flash of light would have been a nuclear explosion.

Today we don't panic as much but will we feel the same if the nutcases in Iran get a nuclear weapon?

Converging Planets and Leonid Meteors

EVENING PLANETS: When the sun goes down tonight, step outside and look southwest. The two brightest planets, Venus and Jupiter, are shining through the twilight side by side. You'll want to keep an eye on these two because they are drawing noticeably closer together every night. Venus and Jupiter are converging on a patch of sky in Sagittarius where they will have a spectacular double-conjunction with the Moon at the end of the month. Don't wait until then, though. Visit spaceweather.com for sky maps and start watching now.

LEONID METEOR WATCH: The Leonid meteor shower peaks this year on Nov. 17th and 18th. Bright moonlight will probably spoil the show, but not necessarily. Researchers who study Comet 55P/Tempel-Tuttle, the source of the Leonids, say Earth is going to pass through one or two of the comet's dusty filaments. Peak rates of 20 to 100 meteors per hour are possible during the early hours of Nov. 17th (especially 0000-0200 UT) and again during the waning hours of Nov. 18th (around 2130 UT). These times favor sky watchers in Europe, Africa, and Asia. Smaller numbers of Leonids could appear between the anticipated peak times. Meteor enthusiasts everywhere should monitor the sky on Nov. 17th and 18th; the hours before local dawn are usually best.

This is a good time to start thinking of Chanukkah, Christmas and Yule gifts. And a telescope might be a good one for your budding astronomer. You can find a good, inexpensive telescope at Edmunds Scientific.
