UFO Sighting in Arlington, Massachusetts – I photographed the horizon three times in a row and a saucer of light appeared in each photo.

At around 11:42pm on july 30th 2020 i heard a noise outside and looked. it was a craft with a strange pattern of lights heading towards the horizon. fifteen minutes later, at around midnight, after the craft was gone and the sound was gone, i grabbed my cell phone and went out to my front porch to photograph the horizon. i took three photos in a row of where the craft had gone, even though i saw nothing in the sky at the time. when i looked at the photos i saw a white saucer of light in each photo. it appeared to move back and forth on the horizon, within a minute.
