That is, if you completed the semi-circle, the sun would not be at the center or even the anti-center.

Update: It turns out that this is what is known as a Circumzenithal Arc. Thanks to the good people at Atmospheric Phenomena for getting back to me with an answer as to what formed this really cool spectra in the sky.
