Blue Eye in the Clouds

It never ceases to amaze me the myriad different shapes clouds can take. Why this oval blue patch existed in an otherwise cloudy sky I'll never know, but I'm thankful to have seen it!

 

P.S. I now know that this is a meteorolgical phenomenum called a Fallstreak Hole and is caused by super-cooled ice-crystals nucleating and falling out of the sky!
