Welcome to the BAUT Forum.

It's not that easy to casually spot the difference between an actual full moon and one that is roughly 93% full, like the night before and the night after the full moon -- or even the one that is 86% full, like two nights before and two after.

I am confident that the cause of what you thought you saw is lack of careful measurement rather than madness.

thanks, but did you see last month it seemed to be more than 86% for more than 5-6 nights and it was at least 86%last night if not 96%.

That difference is hard to see with naked eye. Only clearly visible difference is that the Moon is much brighter during the full moon than only a couple of days before and after.

Last night? OK. According to the US Naval Observatory, the moon is predicted to be full at December 15, 16:15 UTC (GMT). What you saw last night must have been around 86% full on December 13, 16:15 UTC. I don't know your location or when you observed, but it could well have looked "almost" full to you even though it was around two days before 100% fullness.

Take a look at the "Full" Moon through a telescope next time. You'll see that it is only full on one day/night.

The answer here lies in physics. The Moon (or the Sun I suppose), would have to radically change its speed of orbit in order to vary in how long the Earth facing side reflects full solar coverage. That would have been noticeable had it even been plausible.

It has been really pretty near moonrise the last few evenings!

Moon percent illuminated (late afternoon eastern US time)

Dec 12: 91.8%
Dec 13: 96.5%
Dec 14: 99.2%
Dec 15: 99.8%
Dec 16: 98.3%
Dec 17: 95%
Dec 18: 90%

Hum,
it could be that yesterdays full moon was the `highest` Full moon for 18 years.

An event which is of importance to any druids out there...

That's a contradiction, surely. What are your numbers, aurora?

I was using Planetarium, a program for the Palm operating system.

http://www.aho.ch/pilotplanets/

I just double checked, and it says the moon was 96.5% illuminated on Dec 13, 2005 at 4:40 PM Eastern Time.

The US Naval Observatory web site has the following for moon illumination, at midnight Eastern Time:

Dec 12 87%
Dec 13 93%
Dec 14 98%
Dec 15 100%
Dec 16 100%
Dec 17 97%
Dec 18 94%

See a whole table on http://aa.usno.navy.mil/data/docs/MoonFraction.html

Hum,
Apart from the Moon's Nutation Cycle, Moon rises near the autumnal equinox (Which was on September 22nd), the day-to-day difference in the local time of moonrise is about 30 minutes, as opposed to 50 minutes on average throughout the rest of the year.

All these things may conspire to make you to believe that the moon was bigger or fuller than it was.

As a bit of trivia, I believe that the Moon is currently about as far north as it gets in its 19-year-long Metonic cycle.

I saw a blue moon once. I was about 10 years old on a beach in Umzumbi. A fullish moon rose from behind the ocean and it was sky blue. As it climbed it changed colour.

Though it was blue, that's not what's commonly referred to in the phrase once in a blue moon.

The BA corrected that page on January 12, 1999. The second-full-moon-in-a-month idea was the result of a couple errors of interpretation in the pages of Sky and Telescope.
