The Moon Is Upsidedown Tonight ! Las Vegas, Nevada

I do not know your health or your age...I believe at some point you mentioned your were around the half-century mark...All I stated is this...age impacts health and perception...no one is immune to this...

Well my perceptions are fine. This is a bit off topic anyway. When the time comes for a "Check up" I will try to remember where to find my keys to the car.

Yeah, they are...you posted a legit photo in the opener...I was merely commenting on your question concerning whether any of us thought the Moon's behavior was different...IF anything is different, it would more than likely be the observer, the level of understanding, and viewing conditions...that is all I meant...and, that goes for all of us...up to and including, the experts...which I am not...

Its 11_17_11, woke up at 1_30 am.
I went outside for a few and noticed the
moon still looks odd, it should be a full moon
but it looks like its sideways or upside down with
the top cut off, I dont have a good enough camera
to take a picture. But I can confirm with my eyes somethings not right

Why do you think this?:

...it should be a full moon ....

?

Take a look at this site. Based on the time of our post, you are in the Northern Hemisphere, North America, correct?

Moon Phases Calendar

Note that as the Earth rotates, the angle of the terminator (shadow) line will change.

I see it is waning, to just a bit more than half, for this date.

It was almost full a few days ago im in arizona
Im sure im just it a time warp but regardless it looks odd

It was full on Saturday (November 12), and I suppose could be described as "almost full" (but getting less full) for a few days after that. Although, last night it was closer to a gibbous moon, and tonight it will be getting near to being a quarter Moon.

Can you please give a little more detail as to what looked odd about it?

I just took this picture 15 mins ago. It's not a moonset it's the moon rising in the east from Las Vegas

Looks about right, for this date:

Don't be fooled by the orientation in those images, in the Moon phase calendar. The amount of illuminated part is the point in comparison.

The apparent "tilt" is just the result of the perspective of view, at any moment of the night (or day).

Care to explain the tilt ? The tilt is the whole point.

Care to explain the tilt ?

I've been reading through this thread for days. It has been explained already....many, many times.

Don't know why the three-dimensional aspect of the geometry might be difficult to grasp for some. In those cases, maybe the best sort of teaching tool would be some kind of scale model to re-create it visually....since it doesn't seem to be understood in the form of pictures and words on the Internet.

Though, I have seen a few very good videos that explain it perfectly...of course, even a video is "two-D", so there's that real 3-D visualization difficulty aspect again.

Oh, and to add....just to mention, I fired up my Stellarium here on the old 'puter.....set the location over to Las Vegas. Took a gander at the Moon. And sure enough, it looks exactly as it does in your photo, up above.

When I write "exactly" I of course mean the angle of the terminator shadow line on the Moon's surface, and the angle it makes with the Earth horizon. Perfect match.

You said it yourself:

It's not a moonset it's the moon rising in the east from Las Vegas

The ecliptic at Moonrise is now close to perpendicular to the horizon.
The Moon is rising in the east. The Sun rises in the East. The Sun is illuminating the Moon.

The moon rose at 74 degrees east of north. thats 16 degrees north from dead east.Stelarium shows it rising at 82 degrees . thats 8 degrees off to the north. and stelarium says the sun will rise at 113 degrees when it actually rose yesterday at 126 degrees. That in itself is enough to say to me or anyone unbiased that something is wrong. Also the moon tilt is the same tilt seen on the equator.

Are you allowing for magnetic variation? Also called, declination?

That is the difference between Magnetic North, and True North. In Las Vegas, that amount is 14 degrees East.

Remember the ditty, "East is least and West is best". So, with East variation (declination) you subtract the 14° from the True bearing to get the equivalent Magnetic bearing.

You flip the truth better than a cook can flip eggs. The point is not true north or magnetic north THE POINT IS, THE MARK WHERE IT RISES ok? Stelarium shows the same tilt on the equator at the same hour.

reply to post by CherubBaby


I'm not "flipping" any truths. It is what it is:

The point is not true north or magnetic north..

Actually, yes it is....since there was a discrepancy in two readings. It is important to nail down the units of measure in each view you refer to, in order to be on the "same page".

In Stellarium, can you look to see if the bearings they supplied were relative to True North, or Magnetic North?

I presume that the visual sightings personally made of the Moon were done with a compass? Then, that is by definition relative to Magnetic North. The Stellarium "discrepancy" is almost exactly equal to the magnetic declination for your longitude and latitude on the Earth's surface. This would mean that Stellarium was prviding bearings based on True North......

That has nothing to do with the fact that the moon is the same tilt at the equator and it shouldnt be 34 degrees north of the equator. But you know this already

I am in Orange County, California. It is 3 am. Moon is a boat moon shape, almost exact same orientation as the picture from Las Vegas a couple posts above.

I don't know too much about the terminology, but I do know I have never seen this before in my life.

I only noticed it today, after reading this thread.

I don't know why some people sound like this is normal. It's not.

I have never seen this, ever, before I read this thread.

I don't know why some people sound like this is normal. It's not.

It's perfectly normal, at this point in the way the Earth, Moon and Sun relate in their orbits, in three dimensions.

It looks exactly as predicted in the program Stellarium. This is free to download, and it is mathematical and does not need to be online to use it. So, it cannot be "changed" as some people might claim, in order to "hide" anything.

Stellarium tonight matches perfectly.

Reading through this thread, there are many other examples that also confirm that the Moon is quite normal.

reply to post by moonweird


Your right. It's not supposed to look the way it does unless you live on the equator.
