Following my recent observation of subparhelia and sub-PHC on the car windshield earlier in the week, yesterday I had another great catch. Whenever I see altocumulus clouds the first thing that comes to mind are elliptical halos. A large patch of blue sky appeared and looking up, sure enough there was an elliptical halo! I brought the camera and I took a bunch of shots of the halo some of which I present here. I have a feeling the 2018 halo and sky optics season is going to be a good one.
