In this photo taken with
 smartphone camera, a fallstreak hole forms in the sky over Wonthaggi, 
Australia, Monday, Nov. 3, 2014. A fallstreak hole is a circular gap 
that appears in high clouds, when a section of the cloud freezes. The 
ice crystals are heavy, so they fall out of the cloud, leaving a hole. 
It is a relatively rare phenomenon.
