I think I saw a possible UFO while delivering newspapers at 4 AM. Will not disclose the exact location for obvious reasons but i choose some village close to where i work. I just started my route. It was a clear sky with a bright receeding moon (full moon until the night before). As I was walking to a house to deliver a newspaper at 10 past 4 in the night, I was startled by some deers approaching in an adjacent wheat field and then bolting as they discovered me (I clearly saw them retreat a bit and wait for me to go away), thus I was on alert a little bit due to them approaching me when there was usually no one awake in that street normally on that day of the week and especially this time. From observations I made this daily migration route was not unnormal for deers. Right afterwards I gazed up to the moon and spotted a bright dot slowly moving left of it, from my perspective some centimeters left of the moon disk and from "south" to "north" of the disk. I thought it was the ISS at first and stopped looking up, as I had spotted it numerous times already, always backed up by some ISS trackers. Directly afterwards I looked up again and the dot was gone. It made no noise and did not pulsate in any fashion, lasting only for some seconds. There are only a few options. Either it was a satellite, briefly illuminated by the rising sun, while the actual sunrise was still an hour away. But however small the chances of that happening where, i should have been able to see something similar already, given the timespan of me delivering newspapers (again I will not give further details in order to remain anonymous). It could have been a stray falling star, albeit it would have been a very slow one. Slower than what I had seen before. I am not completely convinced that it was an UFO, sticking with the chance illumination of a satellite theory as I do not have enough knowledge to either exclude or prove this possibility. Due to its appearance, this should have been visible in a wider area.
