A month or so I was letting my dogs out the side door like I've done since last century and saw this reflection coming off my window onto the house next door. My memory isn't the greatest but was sure it had never been there before. So I summoned my memory and asked her if she remembers that. NYET!

I told my daughter who lives across town and she took this pic.

Then, because she's smart like her mom, she put a mirror in front of one window to debunk curvature of the window pane as the reason.

looks like normal sun halo or perhaps a sun dog to me. dunno

I dunno either, but I doubt it's a sun dog. According to wiki: The sun dog is a member of the family of halos, caused by the refraction of sunlight by ice crystals in the atmosphere. Sun dogs typically appear as a pair of subtly colored patches of light, around 22° to the left and right of the Sun, and at the same altitude above the horizon as the Sun.

Get some distance from your windows and look at something reflected in them with binoculars. Not the sun if you value your vision. Some trees or something.

The reflection should be distorted.

Should I do the same with a mirror in front of the window?



I use welding lens when staring at the sun.

Someone is under distress, that's the X-men alert symbol.

I was right.

Don't stare at the sun.

The windows are slightly bowed in, you can see that if you get some distance from them. Enough distance for the light rays to get scrambled by the slight bowing. They are acting like a paraboloid, focusing light rays, though it's a crappy paraboloid because windows are rectangular rather than circular. If you google you can read about window reflections melting siding on houses because they focus the sun's rays like a solar oven.

BUT what about the mirror? It didn't come from a fun house.

I don't know what you did with the mirror. So, try or don't try what I am suggesting, but that's my input. Enjoy.
