UFO Sighting in Collierville, Tennessee on 2017-07-09 19:20:00 - Object moved verticle to the horizon up and down.

Taking pictures of the sunset behind clouds on 7/9/2017. we were looking to the west. i did not notice the object until i reviewed the pictures. the pictures were taken on a samsung galaxy s8 phone. the pictures were all taken withing 12 seconds of each other as follows: 071.Jpg - ‎sunday, ‎july ‎09, ‎2017, ‏‎7:20:31 pm - image shows a round object just above the cloud line in the center of the picture. the object is not as clear in image as it is in the others, but, appears to have defined round shape. 072.Jpg - ‎sunday, ‎july ‎09, ‎2017, ‏‎7:20:40 pm - object is well above the cloud line and in line with the highest set of wispy clouds. zooming in it is obvious that this is the same shape as the first image but is more clearly defined when zooming in. 073.Jpg - ‎sunday, ‎july ‎09, ‎2017, ‏‎7:20:42 pm - this image is taken 2 seconds after the previous and the object appears to be significantly lower than the previous image but just a clearly defined when zooming in. initially i thought this may be the moon, however, this was the night of the full moon which was rising in the eastern sky. it looks like a planet or moon to me but, would have to be very large to be that visible...And i can't explain the movement. the angle of the first picture is a little different but, the second two are very similar angles.
