(Aug 9 APOD) Moon ?

[perseus]

My first post on this board although I have been following APOD for the last couple of years.

I was wondering what that bright light in the sky is on todays picture (9th Aug 05). Looks like sun, however sun has to be below horizon. So I suppose it must be moon although full moon looks a bit high just after sun set.

Dear Sirs,

in today’s picture of “Venus belt”, right in the middle of the blue sky, above the sea, is something pale, round, grayish and vague, that might be the full Moon – or is it? But the setting Sun is mentioned, and a full Moon is not, so I am sure many people will be mystified.

Based on the given data the object should be the moon.

Often we are left with out sufficient data about some of the APOD pictures and we must rely on what IS stated. Besides I think that would have been a much better picture for the Earth Sciences POD

Judging from the piers shadow in the water, I would guess that it is the sun. The moon would not be full setting behind the sun. Just my opinion.

I agree, It's probably not the moon (the moon would be full), unless it is an out-of-focus moon, or perhaps an out-of-focus Venus. It looks more like a light artifact than any astrnomical phenomenon. Maybe its a light artifact from a headlight that is off-camera?

Considering one important fact: "The belt of venus appears opposite the sun" it would have to be the moon. The belt of venus is caused by the sun shining through the atmosphere and the earths shadow.

After reviewing the facts. I see that the belt appears after sunset or before sunrise in almost all directions including opposite the sun. I must agree that it has to be the moon.

I'm a novice, so need a clarification on this one. The text says the belt of venus is visible before sunrise or after sunset, but in the picture the sun appears to be in the sky...or am I looking at a full moon?

Yeah, I'm pretty sure that's the moon. The camera lens used for the photo was probably 35mm or so; it wasn't able to capture any detail on the moon's surface.
