I cant say when it happened exactly as I didnt realise it was a ufo at the time. I often work late feeding cattle at midnight and maybe 10 +- 4 years ago I saw a light that orbited my home. The nights were frosty and the cold would clear the sky of cloud so that the milky way and every star was visible. The light was a point source like any star (and as bright as the brightest in the sky) except it would change colour every second or less roughly, it would change green orange yellow, maybe more colours but I forget. I assumed at the time the colour change was due to refraction in the atmosphere, like what makes stars twinkle.
I was a little intrigued by the view and followed its movement. It would slowly move sideways maintaining its distance above the horizon. I think it went counter to the suns direction. I had a lot of time to follow it and though I didnt carry a phone at the time, I guaged it would make a full orbit in about 10-20 minutes. I saw it every night like clockwork for over a month until I forgot about it, as I assumed it was a satellite.
I showed it to my father and asked him what it was and he recalls it also. I would often look for planes at night and they would travel in a straight line or mild curve and be distinguished by their red flashing aircraft beacon. Years later I read about rocketry and learned that objects must orbit the centre of gravity of the earth so from my perspective they would move in a straight line. most rockets have wasted all their fuel in under 10 minutes, therefore it would be impossible for a man made satellite to burn continuously for a month.
And thats all I have sorry, no pics no video, if you want to call me a liar I dont mind, but Im not trying to make money out of it.
