View Full Version : Discussion: Blue Moon On July 31

2004-Jul-09, 06:21 PM
SUMMARY: A Blue Moon is a fairly rare event that happens when there are two full moons in a single month. Since the Moon's cycle lasts 29 days, and most months are 30 or 31 days long, it can happen - usually every 30 months or so. Since there was a full Moon on July 2, the next one will happen on July 31. Of course, the Moon won't actually turn blue - it's just a saying.

What do you think about this story? Post your comments below.

My understanding of the term Blue Moon is that it refers to the second full moon happening while the sun is in a particular astrological sign, so a Blue Moon would have to happen on the 19th or 20th of the month, and would happen more oftern in the June & July timeframe than in December & January. It is a common misconception that it is calendar months with a second full moon.

Note that if it was a calendar reckoning, there would be no Blue Moon this month in Japan and New Zeeland.

In a NASA newsletter I got today there is a reference to the explosion of a volcano called Krakatoa whose dust clouds circled the Earth & produced a blue moon event.
There is a link here: Blue Moon (http://science.nasa.gov/headlines/y2004/07jul_bluemoon.htm?list902052)

Y'all might find this interesting: http://skyandtelescope.com/observing/objec...ticle_127_1.asp (http://skyandtelescope.com/observing/objects/moon/article_127_1.asp)

I've heard this story before, but in a nutshell, the modern belief that a blue moon is the 2nd full moon in a month is due to a mistake in a 1946 issue of Sky & Telescope...

So, let's get this straight. There is NOT a blue moon this month at all!!!

The next Blue moon is in August of 2005.

And yes, I go with the notion that Jan 1st, 2001 was the first day of the new millenium! So there!

:angry: As you Fraser said it, I don't believe a word of it, but will pay attention when I think about its date the right time. Now, it promises a bad summer in Belgium, so? Which us all good luck maybe?
Is this an Australian board? Can't you help me at an aboriginate (or so, I just looked up a much more interesting word for my pocket, that's why I forgot to look up this one) correspondent please?
Would you put my picture online the day I send you one from the sky?

Is it possible if I say, The color of the moon turn blue because the Earth's atmosphere bends some of the blue light from the Sun around the Earth and toward the Moon, hence we see a blue moon...

Blue light? Can we see blue see from the Sun?

I must agree with DippyHippy!!!!!

A recent article at skyandtelescope (the below url) suggests another possible, more likely meaning to the term 'Blue Moon' which relates to farming seasons ie when 4 full moons occur in one season, then the third full moon is said to be the 'Blue Moon' or 'odd one out'. This is a very interesting article and it suitably challanges our modern day notion of what a Blue Moon is. It also discusses the rare occassions when the moon has actually 'turned' blue from various earth events eg volcanic eruptions.
In the southern hemisphere we will experience two full moons in August. So going by the below article, the Blue Moon will be on the 1st August 04.

:lol: It seems like I am the only one who has actually seen a Blue Moon. I was on holiday with my parents at a little place called Umzumbe, on the South Coast of South Africa. Early evening, the moon rose up above the ocean and it was blue...not nearly blue, it was light blue like the blue on this site !

Regardless of when the blue moon "occurs" I'm glad to know what the saying means now, nothing to do with color.

i took that picture of the Blue Moon.
Boy it is everywhere on the Net.
Thanx Fraser for posting it here too.
