Flying fireball in PragueI was walking my dog at night in the street right next to my apartment. Suddenly an orange sphere that looked like it was on fire appeared flying on the street at the top of the building's height. It wasn't too big, maybe 1 foot by 1 foot or bigger, but not too big.I was surprised to see that, and suddenly it turned off and moved up the street where it turned right to my apartment's street. I run to my street and saw it on the narrow street that can be accessed from my street turning left. So the object must have to turned again to get there. I saw that It was like a squared silhouette and then it disappeared, I guess it went flying forwards to the street.It was flying over the buildings, not at high altitude.It was really close to Karlovo Namesti in Prague, Czech Republic.
