Halo 360

As I was about to get into the car after lunch, I spotted a full-circle halo around the sun.

I’m fairly certain it’s a 22º halo based on the size. It would have a 44º diameter, and I worked out the camera has a viewing angle of about 58º at its widest setting.

I took some photos with the good camera when I got back to work, but (believe it or not) I don’t have a USB cable here, so I’ll have to wait until tonight to pick one out and post it.

Here’s the photo I initially took with my cell phone. I grabbed the good camera when I got back to work and took a few more photos, including the one I posted above. I couldn’t transfer the photos over until I got home, so I posted this one to start with.

Edit: It’s not as good a shot, obviously, but it shows something that wasn’t there when I took the follow-up picture: part of a circumscribed halo outside the circle, touching it at the top.

    We just experienced 22 degree rainbow halo around the sun today in the Southcrest section of San Diego at about 12:30 this afternoon pacific time. It is now 2:52 and you could still faintly see it! What an amazing sight. I teach at an elementary school and the kids were all amazed by it. They actually thought aliens or an asteroid was coming to earth.
