Moon 180 degrees out

[IanDSamson]

The moon is waxing, but when viewed, the sun is on the left of the moon, the moon's shadow faces the sun, while the moon's light source appears to be coming in from the right hand side of the window. This indicates to me that the moon is either on the wrong side of the sun, or is 180 degrees out. Turn the moon around by 180 degrees so that it faces the sun, and the moon's shadow faces away from the sun.

Hey, Ian!
Are you in the Northern or Southern hemisphere?

[IanDSamson]

The hemisphere is irrelevant. Light shines onto a surface exactly the same way in either hemisphere and on any other planet in the galaxy!

Hi Ian,

You may or may not be right, but there's bound to be a reason behind Pasha's question.
I would be helpfull if you would just answer his question in order to have him help you.

Pasha,

As far as I could find out Ian is talking about Johannisburg, south Africa, so the Southern Hemisphere.

Hope this helps.
Ian, thank you for your understanding.

The graphic is self-explanatory. The Sun is on the left, the moon on the right. The light on the moon's surface is coming from another light source to the right of the moon, but we all know that the moon reflects light from the sun. Therefore the moon is 180 degrees out. The hemisphere of observation remains irrelevant. If you observe the moon, you will see that the visible portion of the waxing moon faces the sun, with the moon's shadow away from the sun. The shadow of the moon cannot therefore point at the sun.

Ian, I do understand you.
This is an error.
However, I have a suspicion that it only manifests itself when Southern hemisphere location is selected in YoWindow.
That is why I have asked you.

I hope to fix this error as soon as I found time.

[IanDSamson]

The hemisphere is irrelevant.
The moon is setting in Tel Aviv and is the same way around as it is in Johannesburg.
You obviously miss my point.
Check with your local planetarium or university.

Thank you.

Finally, here is sunset in Paris, France. The appearance of the moon is identical to that in Johanneburg a few hours ago. I could go on and on, but I am a Meteorologist as well as a qualified Pilot. I have studied these phenomena for decades.

Yes, again, I admit, there is an error inside YoWindow.
