My wife told me she had heard that yesterday. I didn't think it was true but here is a report from CNN. Scientists: Quake may have made Earth wobble Wednesday, December 29, 2004 Posted: 2:44 PM EST (1944 GMT) Scientists believe that a shift of mass toward the Earth's center during the quake caused the planet to spin 3 microseconds faster and to tilt about an inch on its axis. RELATED * Tsunami death toll tops 71,000 * Scientists: Quake shifts islands * Special Report: Waves of destruction LOS ANGELES, California (Reuters) -- The deadly Asian earthquake may have permanently accelerated the Earth's rotation, shortening days by a fraction of a second and caused the planet to wobble on its axis, U.S. scientists said Tuesday. Richard Gross, a geophysicist with NASA's Jet Propulsion Laboratory in California, theorized that a shift of mass toward the Earth's center during the quake Sunday caused the planet to spin 3 microseconds, or millionths of a second, faster and to tilt about an inch on its axis. When one huge tectonic plate beneath the Indian Ocean was forced below the edge of another "it had the effect of making the Earth more compact and spinning faster," Gross said. Gross said changes predicted by his model probably are too minuscule to be detected by a global positioning satellite network that routinely measures changes in Earth's spin, but said the data may reveal a slight wobble. The Earth's poles travel a circular path that normally varies by about 33 feet , so an added wobble of an inch is unlikely to cause long-term effects, he said. "That continual motion is just used to changing," Gross said. "The rotation is not actually that precise. The Earth does slow down and change its rate of rotation." When those tiny variations accumulate, planetary scientists must add a "leap second" to the end of a year, something that has not been done in many years, Gross said. Scientists have long theorized that changes on the Earth's surface such as tide and groundwater shifts and weather could affect its spin but they have not had precise measurements to prove it, Caltech seismologist Hiroo Kanamori said. "Even for a very large event, the effect is very small," Kanamori said. "It's very difficult to change the rotation rate substantially." -----Original Message----- From: utah-astronomy-bounces+david.dunn=albertsons.com(a)mailman.xmission.com [mailto:utah-astronomy-bounces+david.dunn=albertsons.com@mailman.xmissio n.com] On Behalf Of Cynthia Blue Sent: Thursday, December 30, 2004 8:03 AM To: Utah-Astronomy(a)mailman.xmission.com Subject: [Utah-astronomy] Earth Change?

We need to watch our animals more closely. It seems the animals had a sixth sense about the coming disaster and fled to higher ground before the tsanami hit the beaches. They reported very small animal causualties. I've heard about strange behaviors of animals before earthquakes as well.

Swap Meet
by Paul Johnson 29 Dec '04

29 Dec '04

It sounds as if there is a small handful of people interested in doing a swap meet (as long as nobody gets cold). So why don't we have people post what they have on the list? Everyone gets to participate and everybody stays warm. I think it would work as long as all the offers and follow ups are handled off list. What do you guys think? Paul.

I agree, the socializing is a lot of fun. I always enjoy meeting new people. We ought to have it in conjuction with a Solar Party or something.

Dark-sky site
by Chuck Hards 28 Dec '04

28 Dec '04

After much discussion my wife has decided that family funds will not be allocated to such a project, period. Co-ops and corporations don't fit her ideas on recreational property and privacy. I must drop my efforts completely, and am very sorry to have wasted people's time. Those of you who have contacted me, don't let my situation stop you, please forge ahead without me. I will say that the 2-hr. radius from Salt Lake probably isn't going to turn up much more than compromise sites, from my investigations to date. Let the ridicule and jokes begin. __________________________________ Do you Yahoo!? The all-new My Yahoo! - Get yours free! http://my.yahoo.com

Sucker hole now
by Patrick Wiggins 28 Dec '04

For here near SPOC at least, there's a large sucker hole overhead at the moment that's allowing ok views of the comet. Easy to spot in binos but no sign of the tail I thought I saw a couple of nights ago. I'm trying to get some images but with the Moon up there the sky is pretty washed out. Patrick

Now that Christmas has passed and I did NOT get a green laser pointer, I want to buy one. Has anybody got a strong opinion about the "best" one to buy for under $150.00? Mike
