I got this from a friend at UC/Davis who wrote: START QUOTED STUFF---------------------- This comes from a fairly reliable source on campus. I'm not sure that this full moon will be so much brighter than other December full moons near perigee, but still, it sounds like a record-setter and a remarkable sight. This year will be the first full moon to occur on the winter solstice, Dec 22, commonly called the first day of winter. Since a full moon on the winter solstice occurred in conjunction with a lunar perigee (point in the moon's orbit that is closest to Earth) The moon will appear about 14% larger than it does at apogee (the point in its elliptical orbit that is farthest from the Earth) since the Earth is also several million miles closer to the sun at this time of the year than in the summer, sunlight striking the moon is about 7% stronger making it brighter. Also, this will be the closest perigee of the Moon of the year. On December 21st. 1866 the Lakota Sioux took advantage of this combination of occurrences and staged a devastating retaliatory ambush on soldiers in the Wyoming Territory. In laymen's terms it will be a super bright full moon, much more than the usual AND it hasn't happened this way for 133 years! Our ancestors 133 years ago saw this. Our descendants 100 or so years from now will see this again. I hope someone else might find this interesting! Remember this will happen December 22, 1999. ---------------------END QUOTED STUFF Sounds like a great night for an evening paddle; the waters will have a special silvery luster and shimmer to them. FYI: In the NYC area the moon will rise at around 5pm on Dec 22nd and set at 6am the next morning.

This combination also makes for some stupendous tides and currents. At the Golden Gate Bridge, December 21 shows an excellent high of 7.10 feet at 9:38 AM. I don't have the whole table here but I seem to recall that nearly the lowest low of the whole year follows directly ... a good day to be swept where you want to go, or out to sea like the canoeists in the Everglades. I am taking Dec. 21 off to go paddling if the weather cooperates. jerry.

Maybe in my own mind I will percieve it to be both brighter and larger. Judging by how clear it was a couple of nights ago- best since last year winter- it just may be. Or at least to me.

Matt, You don't understand tides in the least if you believe this. Consider the question: why are there 2 lunar tidal bulges, one on each side of the Earth? If it's just simple matter of the Moon "pulling" on one side, why the bulge on the opposite side? Tides are usually every 12 hours, not every 24. Tides *always* are stretching forces, even with only one tidal body, or with two on the same side. Elementary physics, look it up. And please take your spurious earthquake prediction speculations to some place where it is on topic. This is not the right forum to discuss this, even if there was the slightest merit to your uninformed suggestions.

Except the places where there is one tide every 24 hours. Personally I think the "slosh" effect is the best term and/or way of visualising these abberations. A shallow tray with the opposite ends being alternatively lifted to get the water to slosh back and forth. Dependant on the natural cyle, the "tuning" of the length of the tray versus the timing of the gravitational tides as to whether and what happens. The diagrams in books so often conveniently forget that there are continents, bays and islands complicating the whole thing. Around our bit of coast, about 300 miles of it there is only one spring tide a month and the tidal heights each day make a very ragged graph. Nothing is quite that simple if you want to get down to definitive causes. There are 3 major causes and a mass of minor ones if you want to calculate actual times and heights. NIWA have a good WEB site with movies of tides, I'll track it down if anyone is interested. >And please take your spurious earthquake prediction speculations >to some place where it is on topic.

Bob's objection was the announcement of a catastrophic event predicted to take place on or about a particular day without real knowledge or understanding of physics but using some general knowledge to promote that prediction which is not supported by scientists in the field. Such predictions can and have cost societies in big ways. A good site on this subject is: http://www.users.bigpond.net.au/peterb/y2k.htm One example: the prediciton by astrologers of the rise of the Thames in 1524 to such a height that it would wash away ten thousand houses, all due to a certain alignment of the planets. This bad call caused quite a stir and needless expense.
