46° halo

The 46° is a large, rare halo. It is typically very faint and easily missed, and the 22° halo might not even be bright. It should always be searched for though, very carefully too. The image had to be heavily unsharp masked for it to be seen easily.

  1. When was this taken, last day or so? You seem to specialize in rare halos!

  2. Yes, it was yesterday. It sometimes seems like rare halos are common, because one particular halo might be rare, but different ones can occur close to each other regarding time. I do get quite a few rarities here.
