Understanding Moon Phase

I’ve tried google and AI lol and can’t get a clear understanding to my question about meridian passing.

So, on September 1 at this particular location, the moons meridian passing is at 8:21pm and 22.2°. Does this mean that at its highest point for the night, the moon is only 22.2° above the horizon?

We're going to need exact location with co-ordinates.

You sure that 22.2° isn't the bearing at meridian passing and not the altitude you're thinking off?

The angles in the moon rise and set columns look to be the bearings of the moon rise and set so it could be the same for the meridian passing.
The angle changes from 22.2° to 35.3° in 5 days. Don't think altitude would change that much

I’m not sure lol. I’m extremely unsure. Right after I posted this I remembered the Prime Meridian is a longitudinal mark so if the word is used consistently, it would be the bearing as you suggested.

I didn’t noticed those arrows you mentioned, but that does kind of make sense. One of the days, the arrows are flat which I assume means the moon never crests the horizon?

Meridian passing is "high noon" for the moon. So yeah, that is as high as it gets in the sky that day/night (22.2 degrees above the horizon on September 1st). In the northern hemisphere, this is also due south (due north in the southern hemisphere).

The moon roughly follows the same path as the sun does--offset by 6 months. So the winter moon is relatively high in the sky at meridian passing, the summer moon low. It is kinda confusing how they do it in that screenshot, but the degree notations for rise and set are bearings, and the degree notations for meridian passing are altitude.

So just like at Prudhoe bay in Alaska, where the sun never crests the horizon for 89 days (or whatever it is), the moon would do something similar in the summer up there.

Every once in a while you'll get a day with no meridian crossing due to the fact that it happens beyond the 24-hour window of that particular calendar day (a few minutes before midnight the day before, then a few minutes after midnight the day after. This happens around the full moon.

The moon is cool as hell.

Thank for clarifying!
