I have a question for all the geeks out there: What kind of weather phenomenon creates this pattern on my window? It happens always when it’s below freezing and dry. It only happens on this window, which has no side wall to protect it from... what exactly?
@bigz Well damn, now I want to know too. LoL #Weather #WeatherPhenomena #Geeks Anyone out there know what creates this

@Pineywoozle I’m really clueless, as the window is double glazed, so it can’t have anything to do with the inside. My speculation is either some very strange airflow pattern on the outside, or some even stranger infrared reflection from the inner glass surface 🤷

@bigz @Pineywoozle

It could be that the window is no longer completely sealed and some moisture has gotten inside. If you want, you can check by touching the window from both sides. If it doesn't disturb the pattern, then it's inside the window.

@bruce @Pineywoozle That’s a good point 👆. The window is over 20 yo and used to be filled with argon or something like that. Now I’m absolutely certain there is air and probably some moisture inside, as I see it sometimes in the corners. But this particular (pixie) frost ring is on the outside…

@bigz

I'm still leaning toward the cause being a failed seal, probably on the far edge in the picture. That could, maybe, cause a temperature differential that allows for condensation on the outside.

@bruce Seals aren’t remotely as much fun as pixies. But a ghost seal who failed at being a circus performer, recreating the ball they tried so hard to balance when they were alive just to amuse the pixies…that I can get behind😉

@Pineywoozle

Ooh, maybe it's the work of a selkie!

@bruce I thought about selkies but wouldn’t they just break the window for sport lol
@Pineywoozle
You know about fairy circles... maybe this is like that, but instead of leading to the fae realm, it just drops you a thousand feet under the sea.
@bruce What I’m hearing is that the author of Sponge Bob far from being a marine biologist is actually a Selkie who has it in for Dinkum… plausible.
