Unless you assume it is and add your mirage math

Yeah that’s a never ending discussion you have all kinds of refraction you have looming which brings object up over the horizon and you have sinking as well making object dissapear bottom up

I don’t like those kinds of topics

Too many variables

and look into daytime moon crescents

Moonlight isn't the sun's reflection

very interesting

Oh there’s actually a really fun and simple test you can do with the daytime moon

....

Sometimes it works out and sometimes its off a bit

If you hold a ball up to the moon as close to it as you can. You will see that the terminatorline (light to shadow) always matches that on the moon.

@zep tepi you cant always do that

On a clear day when both the sun and moon are out

Yes but...

?

I will try if there is a waning or waxing daytime crescent and the sun is opposite of the moon if my ball has half a shadow on it...

👍🏻

I can already give you an answer..

I've got a good observation from morning time when the sun was below the horizon (was just getting light) to the east rising....the moon was to the west about 45 degrees above horizon. I documented the moon light was left upper when it should of been left lower

Just try it

I will

You want to hold the ball in a straight line between your eyes and the moon as close as possible. If you know what i mean @United Netherlands

You can’t obviously block the moon with the ball but hold it as close as possible

What if the sun and the moon are opposite of each other in the sky? daytime, what phase does the moon have?

Check out the second half of that video

Can you put a timestamp?

The moon terminator line observation

Its only 2 min

was a week ago here in NL, waxing crescent moon phase

oh:p

1:05

@United Netherlands it doesn’t matter so long as the sun and moon are both out and no clouds blocking the sunlight

Ive made a few of these observations

so full moon?

No it doesn’t matter what phase

You just need a moon in the daytime

I’ll watch it Z

Watch that observation then look all.the time to make your own

Its very interesting
