Explanation: A big, bright, beautiful Full Moon will rise at sunset on Sunday. Its exact full phase (June 23, 11:32 UT) will occur shortly before it reaches perigee, the closest point to Earth in the Moon's orbit, and make it the largest Full Moon of 2013. But such circumstances are not very rare. The full lunar phase falls near the Moon's orbit perigee about every 14 lunar months. That means the following Full Perigee Moon will be on August 10, 2014, the 14th Full Moon after June 23. On May 5, 2012, 14 Full Moons ago, this inspired telescopic night skyscape captured the Full Perigee Moon rising over Cape Sounion, Greece and the ancient Temple of Poseidon.

I don't think the flags had too much (if any) starch in them. They were attached to an L frame. If you look close, you can tell the flag pole runs the whole length of the top. Not being much familiar with starch, i don't know if you can get that kind of wrinkle in a starched flag. OH, wait a minute, if it was starched like my military clothes were, it would flat and straight.
1. First, apologies: This is my first post. I should have put this topic under the existing thread for 22 June 2013. I find no "delete" button, however.
2. If I am not mistaken, the moon's face is generally fixed at rise when seen from any location in the northern hemisphere, and the same for the southern hemisphere. See this random comparison: http://twanight.org/newTWAN/photos/3002197.jpg

Not to worry. One of the moderators will likely move it there soon enough.

No, the apparent angle between the Moon's features and the horizon changes smoothly with latitude.

Well, they were taken at somewhat different latitudes. But more importantly, they were also taken on different dates. The date affects the azimuth of the moonrise, which also affects the angle of the features with respect to the horizon.
(Technical question: How did you insert the Athens image directly into your post? I tried to use the Img tool but it just gave the URL.
I uploaded it directly as an attachment. That feature may not be available to you until you've made a few posts (to prove you're not a spammer).

Yes, I think the difference in latitude would be negligible and would not cause nearly a ninety-degree shift in appearance.
As to date, you may be right. We see nearly a ninety-degree difference in orientation between 22 June and 4 October. If azimuth is the cause of the shift, this would likewise imply nearly a ninety-degree difference in azimuth, which of course does not occur. I will observe the moon here in Florida over the coming months to look for rotation.
I may post another question in a different thread as to the change in orientation of the moon within its daily travel across the sky. Many thanks!
I forgot what software Chris is using but you can easily download a free planetarium software, set your location and date/time and then change the date to 6 months later and see how much the Moon apparently rotates. I just did this with Stellarium and have found no disagreements with what it simulates and the photos you've posted.
(PS - I also see no need to delete any posts here. It's not confusing or wrong enough to require me to do any moderation as far as I can tell. Unless, of course, another mod got to whatever it was before I got here.)
Just call me "geck" because "zilla" is like a last name.

I don't think there was a suggestion to delete anything, just to move the postings to the correct forum.
