The information from Full moon#The Blue Moon should probably merged into this article. BlankVerse ∅ 16:26, 11 Apr 2005 (UTC)

Those definitions of a "blue moon" are of a recent date as the original definition that gave rise to the phrase "once in a blue moon" has been generally forgotten. The original definition related to the moon actually being blue. This occurs when Venus is very close to the Earth and geocentricly on the opposite side of the Moon from the Sun and the sky is very clear. The dark part of the Moon is then illuminated by Venus and appears to be a pale blue color.

I've removed this text from the article Esbat, as it strikes me as being very unlikely -- the full Venus doesn't give off much light -- certainly less than the Earth. Can anyone comment on this?

The Venus explanation is nonsense - Venus is simply not bright enough to illuminate the moon. However, the following explanation of a Blue Moon is one I've heard before; "Although a 'blue moon' doesn't really look blue, there have been times when the moon does seem to have a blue color. This can be caused by dust particles in the atmosphere, which scatter light. The effects of this dust on the light coming from the moon can cause it to appear bluish in color. Fine dust particles are ejected into the Earth's upper atmosphere after large volcanic eruptions, for example. The eruption of the Krakatoa volcano in 1883 gave us one such 'blue moon'. For about 24 months after this volcano exploded, the dust it spewed into the upper atmosphere caused the moon to appear green and blue when viewed from around the world.

[edit] Apogee and full moon ?

maybe once in a blue moon someone will look at this talk page.

I have once read that a "blue moon" refer to a full moon that also occur when the moon is in apogee (the furthest away from earth) this is a combination that only occur about every 50 ? years. Could not find any refrence to it anywhere.

can anyone help ?

As far as I remember there was such a "blue moon" few years ago. The moon was 15% smaller (as seen from earth)

Does this ring a bell to anyone or "what was I smoking?" is the better question to ask ? Zeq 20:33, 12 October 2005 (UTC)

BTW the full moon apogee is at 2014 so may it is every 19-20 years Zeq 20:37, 12 October 2005 (UTC)
