We've got a long and very compelling video of a bright light hovering in the night sky and also surveying the scene, moving about slowly in different directions. The Houston resident who spotted it first thought it was the ISS, which was indeed supposed to pass over the area at that time.
However, when it stopped in mid air, that's when the sky gazer decided to start filming. A helicopter also enters the frame at one point, giving some reference to the strange object and pretty much debunking IT as a helicopter.
The UFO eventually fades away, but by that time, the witness' camera had died.
Here's what he captured:
Here's the witness' description of the sighting, from SightingsReport.com:
It caught my eyes when I thought it was the ISS because it was suppose to pass over head at "10pm Visible: 2 min, Max Height: 76 degrees, Appears: NW, Disappears: SSE", but then it stopped and that is when I pulled over and started filming, facing NNW at Westheimer and Kirkwood Houston, TX. The other object was flashing red but very hard to see and can not catch it on camera. About 10 minutes after filming due to low battery the light slowly dimmed away. In the Video a helicopter was captured giving a perspective on how bright that object is.
