I was working, in the downtown houston area, on 11/23/2016. it was around 3:15 in the afternoon. upon exiting my vehicle, i noticed the reflection of light in the sky. it was stationary, and appeared to change shape. after about 30 to 45 seconds, the object began moving very slowly, to the east/ south east. it made no sound, or was too far away to distinguish sound. elevation did not appear to change. stopped recording video, when visual contact was obstructed by a building. began recording again, when visual was regained. feeling confident that it was moving slow enough to re-aquire, i entered a building. wasnt inside for more than a minute, and when i came back outside, the object was nowhere to be found. i was able to record the object for just over 4 minutes.
