2 Orange lights and a giant white circle spotted in Austin, TXMy friend and I were sitting on a rather higher spot in our neighborhood to gaze at the stars and just hang out. After about a half hour of us talking about random stuff, I noticed a bright orange star looking thing at around 5,000 feet altitude.. But much bigger than a star. When I first saw it I knew it couldn’t be a plane or a shooting star, it was too big and too bright to be either of those. I pointed it out to my friend with a little alarming tone, and he shook it off as a plane.I tried to explain to him that it just couldn’t be a plane and he began to believe me after the object moved about 6,000 feet and vanished. Now we we’re both at an alarming state. We stared at the sky after that non stop and in a few minutes. It re-appeared in its original location and did the exact same thing. Moved a bit more this time and soon vanished again. Now we knew we weren’t imagining stuff. 1 minute later, I spotted a huge bright white circle at about 2,000 feet altitude zooming past at immense speed. It immediately grabbed my attention and I showed my friend. We watched it fly across the sky until it dropped past the horizon. This thing was giant! It’s not possible this was a balloon or any other man made substance...it just doesn't make sense. Meteors aren't that big and neither are comets. And I'm sure at that low altitude it would be on fire. But not a perfect circle. We have no explanation for either of these strange incidents but one more thing happened, soon before the white circle went out of sight a white firework light up at the opposite side of the circle without any sound which was kind of coincidental but I’m not sure that was anything of significance. I know the circle didn't make the firework because it wasn't in the same location. It just wouldn't have made sense.
