We've got a pretty great video of a UFO over Austin from last month (wish I'd snagged it sooner). Anyhow, at first glance, this appears to be a very bright star just hovering a little after sunset. However, if you notice the tree line, you'll see that the white orb actually is moving. But not moving like a balloon would in the wind, and definitely not moving like a plane or a bird. It also doesn't seem to be a helicopter, but any guess is good.
Satellite - no ISS that night apparently? Drone? There was a similar sighting in Austin recently, and there have been other possible drone sightings in Dallas also recently. Let's not be too quick to judge every true UFO a drone - that's just lazy! : - )
Here's the full video, not uploaded by the witness, but a UFO collecting account:
