This mysterious ball of light UFO which has been seen as far as Nevada in recent days is being explained by NASA as a satellite that is falling back into Earths atmosphere over the following days. ABC news in Phoenix is covering this story and one of their own Anchormen took the first two photos you see in this story. Multiple witness, multiple photos and videos. The news thinks it could also have been a meteor but I have seen a meteor dozens of times and they happen so fast, they do not look like white balls of light but a big green/blue/red blast.
Skip the first 4 seconds or you suffer through bars and tone, really annoying.
