Last night, my friends and I saw a moon halo. this one in fact: http://lancekatigbak.tumblr.com/post/1619163570/havent-had-anything-new-to-post-for-the-longest

We were very intrigued cause we've never seen anything like it before, so I looked it up, and it signified that bad weather is coming. Then I came across a site where people posted that they have seen moon halos in the US, or England, or Sweden, and I'm in the Philippines; so what does it mean, if it means anything?
