UFO Sighting in Oxford, England on 2017-06-09 17:30:00 - A small disk passed from left to right while i was standing in tesco carpark. it disappeared behind a building and did not come out the other side.

A friend and i were on our way to tesco, after which we were planning to go on to an evening picnic. when we made it to the carpark (facing tesco and the white rabbit pub), my friend pointed to the sky, and we both observed a disk like object pass from left to right. it was small, disk shaped object, that in fact looked a little like a flying saucer sweet! at first i thought it must have been a balloon-craft (it could perhaps have been a zepplin?) but it was too far away. it was very fast, and maintained a strangely path. it was a dully blue on top, and a dull yellow underneath. the evening light seemed to shine off the bottom. i could not make out any windows, only a domed shape on the top and the bottom. it disappeared behind a building to our left and did not come out the other side. i can only assume it changed direction. my friend and i looked at each other, shocked! we could not believe what we had seen and started guessing at plausible explanations. we did not know who to go to until we found this site! we are planning to go back when university starts again to try and catch it again, and take a photo if we see anything. we were heading to a picnic to celebrate the full moon. we thought that maybe the full moon may have some connection to what we saw. we would love some feedback to put this idea to rest in our heads if this is possible!
