I don’t want to make anyone nervous, but what the heck is going on with Google Maps? Some people found UFOs everywhere, they move from place to place, no shadows, looks like glowing, and they look metallic. If this is a joke from Google, is a bad one (I don’t know how safe I would feel if I know there is something in a satellite photo over my home that appears to be invisible for human eyes)
This is one of the photos people found:

And here’s the link
Here is the same one but closer:

Someone may think this is funny, but again, the United States had a terrorist attack over 9/11 (I presume people at Google remember this right?) if they are uploading fake “UFOs”, people, is not funny, citizens may get scared just because someone wanted to be funny.
If not, if that’s something that really appeared there, it may be a meteorologic balloon, or something else (like something in the lens of the satellite) and there is no reason to be alarmed. It’s very unlikely that what we are seeing there on those pics, and here, and here are flying disks with martians inside playing poker; but for the other hand, it appears the anomaly only appear one day, and the next one has moved to a different position, and in some cases, it is gone for good.
What the heck!

Could be. Kind of looks like a cloud though.
