The first picture looked like a blue horseshoe shape. While I was waiting on sunrise I kept watching it and it looked like the horseshoe shape turned white and "broke off" even though it was already "off".

Is this a shadow it's casting on the white area of the sky?

Is this considered a fallstreak? DSC08656.JPG

No. That's just a regular hole in the clouds, with a ray of sunlight. You can see the cloud layer is a thicker stratocumulus deck - which does not make fallstreak holes. Instead there just happens to be a few holes in the layer.

Fallstreak holes form in higher thinner layers, where the cloud is supercooled (below freezing but still liquid).

Cool. Thanks for your time!
