Moon halo
Tonight isn't the clearest night of the year despite being very chilly. It isn't good for observing as there is quite a lot of high-level wispy cloud and plenty of airplane contrails. However, I had just got on my bicycle to go home from work when I saw a pretty amazing sight in the sky. Luckily I wasn't going fast, so I managed to stop before I went into a nearby hedge. That'll teach me to look up at the night sky whilst cycling. But what did I see? There was the Moon in the east with Mars about 20 degrees or so away around to the right. Near Mars was something that looked a bit like a curved vapour trail. Looking more carefully I realised that it made a full loop of the Moon. This was no vapour trail but a Moon halo.

The other feature of the photograph is a airplane contrail that was created as I was setting up my camera. If you look carefully, you can see that it even cast a shadow on the clouds below!

I was driving up my drive way when I saw it. So amazing and very clear. I had never seen a halo so perfect around the moon before. I wish I would of taken a picture. Awsome shot!

Tonight(April 7,2005), my husband and I was outside looking up at the sky while he smoked his cigarette. We both looked at the moon. It was odd that we both saw this circular ring around the moon at the same time. He asked me if I could see and I told him that I could so he did not feel like he was going crazy. It was totally amazing to see it. I continue to be totally in ah about how amazing God is.

At 2:30 last night (Nov. 24 2007) I got a call from a freind telling me to look in the sky. So I came out and this is what I saw. I don't know how many others saw it, I haven't heard anything about it anywhere. It was one of the most beautiful things I've ever seen though!

At about 12:30am on Sunday November 25,2007,I got a call from my mother to go outside and look at the Moon. When I went outside to look and I saw a bright ring around the moon that was so beautiful and amazing,but yet very scary at the same time! This is the first time I had ever seen anything like this. So I started to search the Internet and I found this,"AWESOME PICTURE"! Seen here in Fresno California.

Did anyone see the moon halo in North Norfolk 2nd May at 10.35 pm BST? Can you often see a halo on a half moon?

Four years later, and this site still offered the best explanation for this phenomenon that we could find, so thanks, Stuart! We have a beautiful example tonight in the skies above Melbourne (Australia) and it was great to learn more about it,

I saw one of these at about 12AM Dec 3rd, 2009. I live in Palm City/ Stuart, Florida. I was amazed by this phenomenon. The moon was directly overhead, so I laid on my driveway and it was as if I was on the moon looking at some other object in space. Almost like the moon had formed a black hole. It was truly one of the most awesome things I have ever witnessed but my camera would not capture anything but a bright dot with all black around. I guess this is not totally uncommon, as I saw someone in Australia has a post from not long ago and there are quite a few others. But to witness it is truly a blessing. Thank you God!

I just saw my first moon halo! I'm in Orlando and It's about 4am. The most beautiful thing I have ever seen. Great way to start off 2010

5 years later and people are still googling "moon halo" and reaching your great picture and explanation. Tonight we had an amazing one over the clear winter skies in the Galilee in Israel. This by the way the full moon of our holiday known as the New Year for the trees

Thanks for educating me about a moon halo. I saw my first one January 29, 2010 while vacationing in Fort Myers Beach, FL (SW Florida). Very beautiful and mysterious. I was able to get a picture although I don't see any color in my photo, but the ring is visible. How large of an area can see a moon halo? Or is it stricly dependent on the type of clouds overhead? Thanks for making your info available to us!
