UFO Sighting in Two Hills, Alberta

To be clear this sighting was at Lac Santé, in between St. Paul and Two Hills. Please make sure marking is in the correct spot on the map. Ive seen many ufo's here, but I will report 1. Was late at night sitting by the fire when i looked up and saw a circled shape thing, I couldn't quite see what is was but i could see it reflecting off of the fire light, I didn't have any glow which is odd as ufo's usually release a corona discharge. The ufo was in the air about 20-50 feet just hovering but also shaking, think of putting a ping pong ball inside of a bucket or bottle and shaking it, the ping pong ball representing the ufo, was moving at insane speeds back and forth (shaking) I was watching this thing as well as 4 of my friends for an easy 5 minutes straight
