Location of sighting: Calgary, Canada
This is an intriguing UFO. It partly cloaks several times in the video. Do not assume that its changing shape. Big misconception. Its just the cloak activates when their is a blue background. Notice the photo below, the UFO is in a white cloud, however the top 20% of the UFO is missing and there is a partial blue background on that part. Cloud orbs cloak like this when seen up close. Cool sighting.
I trimmed the footage to just show the orb, others that were rimed were fiddling with the camera before the shot.
