DALLAS, TX – A large fireball was spotted by hundreds of citizens Sunday morning, but local authorities have found no evidence to explain what it was.

Police stations from Dallas to Austin were flooded with calls describing a large egg-shaped fireball spotted in the sky. A sonic boom was also reported to have been heard, yet authorities have not been able to locate any debris on the ground. Although they are stressing it is not a result of last week’s US and Russian satellite collision, they cannot say what it definitely was.
