Upside down moon




The moon fascinates me.

We had an upside moon last night which I saw from our sitting room window. I immediately went outside and standing snapping. The photo is from last night, the text from last year, January 18th:

An upside down moon is a result of the moon's orbit around the earth, and the earth's orbit around the sun. And exactly when you see the moon in the shape of a U (lit on the bottom) rather than a backward C depends on what latitude you are at.

We see the moon in the night sky because it is reflecting light from the sun. So the lit part of the moon always points towards the sun. As the earth travels around the sun, the tilt of the earth on its axis sometimes points the northern hemisphere towards the sun and sometimes points the southern hemisphere towards the sun. But this also changes the apparent path of the moon across the night sky when you are on earth looking out at it.  Sometimes it travels at an angle towards the horizon and sometimes it travels straight down toward the horizon. When the crescent moon travels straight down the horizon, you will get the U shaped moon. This can happen once or twice a year, depending on the latitude of your location.

  18. I was searching for upside moon.and found this site, glad i'm not alone. I saw it in Türkiye last night 25/03/2023 It was really freaking. The crescent was downwards. I don't recall i have seen moon like this before. What's happening? I search the phases on northern hemisphere but there is no phase like this. If something has changed they must let us know.

  19. Seeing in Owensboro Kentucky tonight 3/26/23. I've been saying for years now that is not our moon. When I was little all I did was talk to the man in the moon for hours every night. Even long after I found out he wasn't real still found myself in conversation with him often. I've never been more familiar with something like the way grandma's house smells or how you know your mother hands. I noticed it changed over night he wasnt the same there were dark spots where there shouldn't be and light where there once was dark. Now I understand something impacting it and cratering a dark spot but how did the once dark spot become filled in maybe I'm tripping but I'll swear it till I die. That's not our same moon.

  24. Here is one more. It's 21/06/2023 and there's this upside down moon here in Indonesia, Southeast Asia. It's the first time for me to see this kind of moon. I was totally gobsmacked and thought there was something wrong with my eyes. Almost thinking it was a sign of something bad that's about to happen. So glad to hear an explanation for this phenomenon.
