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.
