Under twilight conditions (such that we can see the landscape illuminated and the sky as blue), a full Moon will always be near the horizon.
I have trouble visualizing this stuff. So if the moon was full, but high in the sky, that would mean that the sun would have to be well below the horizon, and thus the sky would be dark?
Yup. A full Moon means that the Moon and Sun are on opposite sides of the Earth. The Moon crosses the meridian at about local midnight. (At high latitudes, of course, the Moon might always be pretty low in the sky.)
Ok, that makes sense.

I think the bulk of them are taken when the moon is low in the sky. Not exactly sure how high the moon is in this APOD, but the text does say "the moon rose just before sunset", which might imply it was still low at the time of the pic.

A Pink moon can probably be seen whenever

April full moon! Here is an image of a pink moon!

OK; but, this one with the cherry blossoms actually loos like it may be pink! :lol2:

Probably just an optical illusion caused by the surrounding pink flowers?

I took the flowers out, and I still think it look kinda pink! :yes:
Maybe though; that it could be only my impression!

Hard to tell the pink appearance if the moon with the
cherry blossoms surrounding it! :) Nice photo!
Contrary to popular misconception, I don't think it's color is why it's called a pink moon. From the link - https://solarsystem.nasa.gov/news/1818/ ... pink-moon/
In the 1930s the Maine Farmer's Almanac began publishing American Indian Moon names for the months of the year. According to this almanac, as the full Moon in April, this is the Pink Moon, named after the herb moss pink, also known as creeping phlox, moss phlox, or mountain phlox. The plant is native to the eastern United States and is one of the earliest widespread flowers of spring.

Channeling my inner neufer, here's a relaxing and appropriate song:

Click to play embedded YouTube video.
I saw it written and I saw it say
Pink moon is on its way
And none of you stand so tall
Pink moon gonna get you all
It's a pink moon
It's a pink, pink, pink, pink, pink moon.

I believe that there is more to consider than just the moon's elliptical orbit when considering it's apparent brightness. Like the sun, the moon changes its position in the sky with the seasons. Unlike the sun, the (full) moon is highest in the sky during winter, and lowest in the sky during summer. Thus a full moon appears brighter in the winter.

Well, thank you, Moon. If you hadn't been there to provide stabilizing influence for the Earth, then maybe, who knows, there wouldn't have been any cherry blossoms on the Earth.

Or a lot of other life forms, either.

Image Pink and the Perigee Moon

Explanation: On April 25 a nearly full moon rose just before sunset. Welcomed in a clear blue sky and framed by cherry blossoms, its familiar face was captured in this snapshot from Leith, Edinburgh, Scotland. Known to some as a Pink Moon, April's full lunar phase occurred with the moon near perigee. That's the closest point in its not-quite-circular orbit around planet Earth, making this Pink Moon one of the closest and brightest full moons of the year. If you missed it, don't worry. Your next chance to see a full perigee moon will be on May 26. Known to some as a Flower Moon, May's full moon will actually be closer to you than April's by about 98 miles (158 kilometers), or about 0.04% the distance from the Earth to the Moon at perigee.
