"Martin" wrote in message ... "OG" wrote in For any randomly chosen place what proportion of the time is Uranus not within 15 degrees of the meridian and/or horizon? When you say 15 degrees what do you mean? 15 deg in right ascension from the meridian/horizon 15 deg in ecliptic from meridian/horizon 15 deg altitude from horizon Each requires a differnt mathematical approach and comes up with differnt frequencies. Martin That's fine - any one of those will be welcome. Just so we have a figure that we can judge against the observed frequency. We can then go back and check the results against C Ezekwe's proposition. Owen |

Early last century, some geophysicists were said to have noticed that Uranus was often located within 15 degrees of meridians of epicenters in the most powerful earthquakes, far more frequently than chance would allow. This hint spurred me to conduct a study into records of later earthquakes, especially, those of magnitude 6.5 (in the Richter scale) and above. My research has indicated that, Uranus is also frequently located within 15 degrees of the celestial horizon of epicenters, in earthquakes of strong magnitude. Using the publications of USGS NEIC, I have prepared A statistical analysis at: HTTP://WWW.GEOCITIES.COM/CEZASTRON/2003stron.htm The analysis shows that in the twenty cases of earthquakes of the 6.5-and-greater magnitude -- covering the period January 1 to June 16, 2003 -- Uranus featured, in 13 occasions, within 15 degrees of the horizon or meridian. Sorry, pure coincidence... There are so many bodies in the Solar System and so many earthquakes on Earth that if you look long enough, you will always find coincidences like this one. Besides, 13 occurences in 20 events is not very convincing, statisticaly speaking... Good night! Benoît Morrissette |

I'm sorry, I was hoping for a number. The original proposition is that "Uranus is near the horizon/meridian more often than expected". Unless you or the OP can calculate the proportion of time that uranus is near the horizon, then how do we know if the figures are significant? No disagreement he IIANM not only do we need to know the expected value, but also something about the distribution, e.g. its variance. I was just pointing out that it's not at all a straightforward matter to characterize it, particularly since the two 'parameters' are not independent. -- Odysseus |

ANSWERS
What is the frequency you would expect? ANSWER: I EXPECT ANY PLANET TO STAY WITHIN 15 DEGREES 33.33% OF THE TIME(BY MATH CALCULATION). For any randomly chosen place what proportion of the time is Uranus not within 15 degrees of the meridian and/or horizon? ANSWER: MOST OF THE TIME Uranus (like all planets) stays relatively close to the ecliptic, so its not as though it wanders aimlessly over the sky. ANSWER: YES Have you done a similar study for other planets? ANSWER: YES, SOME PLANETS, LIKE PLUTO, STAY MORE 33.33% WITHIN THAT RANGE, BUT NOT CLOSE ENOUGH TO THE FREQUENCY OF THAT OF URANUS' -- C.
