I was on my local field. beautiful sunny day. a few clouds. excellent visibilty. i was looking up when i noticed an extremely fast moving point of light. i was amazed and kept my gaze very firmly on this object until after about 5 or 6 seconds it had traversed the whole sky and was at the limit of my vision. it was so far now it was simply too far to see. there was no sound at all. object was simply a round light. very high, much bigger than a star. flight path seemed erratic at the final 2-3 secs. hard to judge the speed. based on planes at height this was perhaps 10 times faster? a few thousand mph i would have thought. it was not a meteor, no trail, seemed to be flying under control. i was aware my good camera phone was a few paces away, but at the speed this was going, i had zero time but to observe, which i carefully did. interestingly a few minutes before this fast object, i noted with interest 2 very high slow.Moving lights which i filmed and observed for several minutes. one was going from bright to invisible for several cycles. i am at loss to say what these were, i guessed some sort of balloon? i got disinterested watching them.Very odd that a few minutes later i saw this fast moving ufo. this is my first ever seen ufo where i have no doubt it was something unexplainable. it was awesome!
