YT2095 Posted May 30, 2007 Share Posted May 30, 2007 the title says it all, Tomorrow May 31`st we will have our Second full moon this month lets hope it`s a clear sky so that we can see this, it`s quite a rare event, one might say it only happens once in a Blue Moon Link to comment Share on other sites More sharing options...
Royston Posted May 30, 2007 Share Posted May 30, 2007 Has this been pinpointed to a recent event e.g volcanic eruption. For anyone interested, the absorption of radiation projected from the moon is thought to be the cause of this, rather than scattering, and the blue effect is only achieved by dust particles of a certain size. Unless anyone knows of any other explanations. Link to comment Share on other sites More sharing options...
JohnF Posted May 30, 2007 Share Posted May 30, 2007 It's not caused by dust particles. It's caused by part of Earth's sky that is constantly leaking in to space being picked up by the gravity of the moon. At the moment most of the leaking sky is blue sky. Because the moon has collected mostly blue sky this time, it takes on a slight blue colour Link to comment Share on other sites More sharing options...

insane_alien Posted May 30, 2007 Share Posted May 30, 2007 don't worry bout it snail. but you're right about physically blue moons being caused by dust particles. only difference with those is its not a predictable event. Link to comment Share on other sites More sharing options...
YT2095 Posted May 30, 2007 Author Share Posted May 30, 2007 that`s Ok, I apologise for the 15 point troll warning I gave you, and the Temp Ban that will kick in on Thursday Friends? Link to comment Share on other sites More sharing options...
grifter Posted May 30, 2007 Share Posted May 30, 2007 Apparently there are only 41 months that have two Full Moons in every century, next time someone says once in a blue moon, you know what the odds are [math]\frac{41}{12\times100} = \frac{7}{600} or ~0.01666...[/math] p.s. 41 months per century is on average data from: http://www.obliquity.com/astro/bluemoon.html Link to comment Share on other sites More sharing options...
Royston Posted May 30, 2007 Share Posted May 30, 2007 Just to redeem myself, the slight discrepancy between the lunar and solar cycles is why we have a 'calendar' blue moon. Link to comment Share on other sites More sharing options...

Spyman Posted May 31, 2007 Share Posted May 31, 2007 It was not until the year 1999 that the origin of the calendrical term "Blue Moon" was at long last discovered. It was during the time frame from 1932 through 1957 that the Maine Farmers' Almanac suggested that if one of the four seasons (winter, spring, summer or fall) contained four full Moons instead of the usual three, that the third full Moon should be called a "Blue Moon." But thanks to a couple of misinterpretations of this arcane rule, first by a writer in a 1946 issue of Sky & Telescope magazine, and much later, in 1980 in a syndicated radio program, it now appears that the second full Moon in a month is the one that's now popularly accepted as the definition of a "Blue Moon." This time around, the Moon will turn full on May 31 at 9:04 p.m. Eastern Daylight Time (6:04 p.m. Pacific Daylight Time). But for those living in Europe, Africa, Asia and Australia, that same full Moon occurs after midnight, on the calendar date of June 1. So in these regions of world, this will not be second of two full Moons in May, but the first of two full Moons in June. So, if (for example) you live London, you'll have to wait until June 30 to declare that the Moon is "officially" blue. http://www.space.com/spacewatch/070525_ns_blue_moon.html Link to comment Share on other sites More sharing options...
