large clear ball shaped orb in Glendale.. day time sightingIn my back yard facing West at 11 am.. I saw out of the corner of my eye a large , white, clear ball shaped unknown object. It moved VERY fast from the South behind me and stopped in the North East sky and hovard for about 30 seconds. I have never seen anything like it.. It was almost clear. Like looking at a mirage or a jellyfish, but in a perfect ball. It then sped up going East for a few miles then turned West and shot off .. It was not a balloon.. I saw another report from Queen Creek Az..25 mins before this I did see a strange flat , black helicopter going Northwest- Right where the orb shot off to.. I took photos but they were to fuzzy.I found it interesting that two people from across the valley see the same weird object. I felt like it was observing me.. It moved almost like a hummingbird does.
