Diamond over Great falls, MT

The report, as filed

I was standing on my porch at around 10:58 pm, and I was trying to see a star because it was flashing. I assumed that it was either a star or a satellite, so I stepped off of my porch to record it better. As I was recording, I could see something slowly hover over my house, and turned my camera to face it. It was slowly moving, but faster than a drone and higher than a drone. As I was filming, it moved slowly and it looked like there was a top and bottom light flashing red every second. There was only one, and I was the only one out there. It wasn’t moving very fast and i could only see it moving and the lights on it. The lights looked like a triangle, but those were only the yellow lights. It only moved for a few more minutes until it stopped right next to the star that I had been recording minutes prior. The night before this, I heard a large whirring sound that sounded like heavy machinery in the sky, but it lasted for about 6 minutes. Each time I have recorded, it seems like there has been a filter over my camera, but it’s never like that normally. Once it had stopped, I could no longer film it and then I had also started to hear thumps near my house or heavy machinery starting. I was not able to capture anymore. The last image uploaded is circled, which is where the UFO stopped when i decided to stop recording. The other one that isn’t circled is the star I was trying to record while it was flashing.
