AlIt was bout 3 weeks ago at midday, and a couple clouds in the sky. I was in the car with my girlfriend and she was driving us to the gym on a busy main road, (Te Rapa straight) and I was looking out the window and I saw this solid white ball in the sky about 200 metres away, (220 yards) and about 100 meters above the ground. At first I thought it was a balloon but I realised it was too big… it looked to be about half the size of a small car and it wasn't moving. It was just staying there stationary, not floating up or down. It was close enough to see that it wasn't moving, as it slightly moved north as we drove south along the road. I was observing this ball for about 5 to 10 seconds straight and was perplexed and confused by it and then we passed a tree on the side of the road and as we came to the other side of the tree which only took 1 second, the ball was gone. It had disappeared right under my nose and I was amazed. This was one of the strangest things I've seen in my life and I believe I witnessed a UFO! Please, if anyone has seen something similar to this, do you have any answers? I know things don't just float in the sky and disappear after a second. Maybe it noticed that it had been detected? I don't know… I just wanted to share. Cheers guys!
