I saw it last night. As a matter of fact it was a day moon so you could see it all day long!

Fun fact: Yesterday I filmed the sunset just for the heck of it. :)

Unless I'm mistaken, a full moon rises at roughly the same time as the sunset. In order for the moon to be fully illuminated, it has to be on the opposite side of the sky as the sun, with us in the middle.

Glance (for Buffalo, NY) : sunset: 6:00, moonrise (night of the full moon) 6:13. Not exactly the same, but also, the precise time of the full moon isn't during the night for my longitude.

Ummm, I'm pretty sure you couldn't see it all day long. Prior to the full moon, it's a waxing gibbous moon, which is seen later in the afternoon and most of the night. The fuller it gets, the closer to sunset it rises.

I see day moons at least once every 30 days or so. Come to think of it maybe they arent full.

The full moon can occur any time during the day, same with the new moon. In fact here in California the full moon was at 12:26pm, many hours before sunset.

The full depends on the the moons rotation around the earth. The rotation of the earth around its axis, which determine sunrise and sunset and not relevant.

You see roughly the same part of the moon all the time - the same side of the moon is always facing the Earth. 50% of the moon is lit by sunlight. The only way for the 50% to be lit by sunlight and seen from earth is for the sun to be behind you.

The "official" full moon time was 12:26pm - that doesn't mean it was visible from California at that time. It wasn't.

On another note, wtf? Seriously, wtf? It's the same ball in the sky day after day, night after night. You people haven't figured out patterns to it in the 20+ years that you've been alive?! I guess you'd have to put the controller down, get out of mommy's basement, go outside, and look up.

When I got up yesterday around 6:30am, the full moon was just above the Western horizon.
When I got home at 6:30pm, it was just above the Eastern horizon.
As the night progressed, it was rising towards the West again.

This really confused me. It basically looked like it was bouncing between Eastern/Western horizons.

I really need to look up the moon's path, because I thought it fully rotated around the Earth, like Earth to the sun.

Another key to understanding moon phases is to remember that, like the sun and all the planets and stars, the moon rises in the east and sets in the west each and every day. It has to. The rising and setting of all celestial objects is due to Earth’s continuous spin beneath the sky.
Wow, ok. I must have remembered it wrong.

More on daytime moons:

http://earthsky.org/space/when-can-you-see-a-daytime-moon

We get many comments from those who see the moon in the daytime. The comments tend to have an air of disbelief about them, typically going something like this:
I saw the moon in a blue sky. Why? How can this happen? I thought the moon was visible only at night!
In fact, the moon is up in the daytime as often as at night. It’s only the full moon that that rises in the east as the sun is setting in the west and reigns in the sky all night long. That means the moon is up all night long only one night each month. Otherwise, the moon rises and sets on its own schedule, having nothing to do with sunrise or sunset, and varying in a systematic way throughout each month as the moon pursues its monthly orbit around Earth. If you want to understand more about the moon’s rising and setting times, and subsequent phases, check out this post: Understanding moon phases
So when can you see the moon in the daytime? Basically, you need three things to see the daytime moon:

  • Look within a week or so of the date of full moon.
  • Before full moon, look for the daytime moon in the afternoon.
  • After full moon, look for the daytime moon in the morning.
  • Look up! The daytime moon is often up there, but it’s pale against the blue sky.


A daytime moon on January 28, 2013 as seen by EarthSky Facebook friend Denise Johnson in Ridgecrest, California, in the Mojave Desert. Notice that this moon in this photo is closer to the (western) horizon at sunrise than the moon one day later (photo below). Full moon was January 27. Afterwards, the moon is waning again and inching closer to the sun on the sky’s dome.

Waning gibbous moon in the west around the time of sunrise, as captured by EarthSky Facebook friend Royce Malacaman in the Philippiines. Thank you, Royce. View larger.

At this writing (January 29, 2013), the moon is appearing in a waning gibbous phase in the morning sky, and it is indeed far enough from the sun to be visible in daylight as the photo above shows. The last full moon was January 27, 2013 at 4:38 UTC. So if you’re reading this on January 29, you should be able to see a daytime moon in the west for another few days.

If you begin to look at the sky a lot, you’ll often see the daytime moon, too. Everyone loves to see the daytime moon. It’s beautiful and serene, floating against the blue sky. Once, a reader in Kansas City wrote in with the name children’s moon to describe a moon visible during the day. She said this name stemmed from the idea that children can’t stay up at night late enough to see the moon when it appears only in darkness.

Daytime moon

That story prompted another reader to send in an alternate version for the origin of the name children’s moon. She wrote:
I heard a daytime moon was called a ‘children’s moon’ because their eyes were sharp enough to pick it out, where the old folks, with fading vision, could not tell it from the clouds.
Bottom line: You can see the moon during the day whenever it’s fairly large in phase and fairly far from the sun on the sky’s dome. So you need to know the date of full moon to know when to see a daytime moon. Learn the date of the next (or last) full moon, then start to look for the daytime moon about a week before full moon, in the afternoon sky. After full moon, look again for a week or so, this time in the morning sky. Most important criterion: look up! If you do, you’ll often see the moon in the day.

That's impossible!

Genesis 1:16 "And God made the two great lights—the greater light to rule the day and the lesser light to rule the night—and the stars."

See, it says so right in the Bible - the moon is out at night, and the sun during the day. The Bible is infallible. </joking>

I know the day of the full moon, the moon rises close to sunset, my point was the moon at moon rise is not when it is most full. If the moon is directly behind the earth at 11pm California time, that is when it will seem most full in California, not at moon rise. But that night the moon will rise close to sunset.

Then you made that point in a ridiculous way, because you responded to my point that you can't see the full moon during the day, with a time shortly after noon for California. It was full for everyone at that moment (well, adjusted to each person's time zone; for me, it would have been after 3pm.)

Here's what I said:
Ummm, I'm pretty sure you couldn't see it all day long.
Here's your reply (in which you quoted me):
The full moon can occur any time during the day, same with the new moon. In fact here in California the full moon was at 12:26pm, many hours before sunset.

The proximity of those two statements implies that you thought you could see the moon at 12:26pm in California.
