dim light close to venus quickly becoming brighter than venus and then fading away. happened total of approx 10 times

i was looking at venus which was very bright. and to the right of venus i saw a dim light which rapidly become brighter and faded again. it appeared the light was traveling in the sky. once it would disappear, the dim light would reappear again, get brighter (noticeably brighter than venus) and fade back out over a 3 second period. every time the dim light would reappear it would start over again in the same spot the original dim light would appear. we watched this "loop cycle" of 3 passes of the dim light appearing, getting increasing brighter and fading again. then there would be nothing for a few minutes only to have the loop cycle start over again. we live near an airport and are very familiar with aircraft sights and sounds, this was not a plane. and due to the tree line it was above, it was very easy to track the path of the light and notice that every time it started over, it was from the same spot in the sky. so just to clarify it was not a! light traveling in a long line, increasing and fading in brightness. this light always started at the same location and ended in the same location
