The best cloud
Most of the time, Mother Nature can be a scary force to reckon with. Tornadoes, tsunamis, and the countless predators that look at humans as delicious meals are very good reasons why we shouldn’t take nature lightly. However, there are times when our planet can leave us downright surprised, in a good way.
This is one of those ways. The OP had no idea what was up with that one particular cloud that day, so he asked the internet. An avid cloud watcher informed him that this is a lenticular cloud, which might also be the very thing people mistake for UFOs. Yeah, we get it.
