I just saw something really weird in the sky.

It was around 12:05. I didn't have a watch on me at the time. I was walking my dog and we were in this big field. I was facing south and turned around. Right in the middle of the sky I saw pic related going by, It was going at a steady pace and was visible for about a minute. It didn't seem to be following the curve of the horizon, but rather moving tangentially to the sky. It continued on Eastward and it didn't disappear behind the horizon but just gradually became dimmer and dimmer until I couldn't see it anymore. I'm half an hour southwest of Minneapolis.

Has anyone seen anything like this before?
