After analysis, we are unable to find any explanation for the shadow that appears moving from right to left across the top of this video. The windows in the background were either closed or (the dormers) cannot be opened. The shadow is not an insect near the camera lens. It is not smoke. It is, in fact, not anything that we are able to identify. We grade this video A–Probably Authentic. The shadow appears in the video of Linda Moulton Howe’s regular weekly live YouTube broadcast for October 3, 2018.
