I'm not 100% sure that what I saw was a fireball, but I saw what literally looked like a ball of fire move across the sky and then disappear on either 9/22 or 9/23. It seemed to extinguish in the air after about 1 or 2 seconds. I saw an article online and realized that there was a report of a fireball in Eastern PA (northeast of where I was) and since I was facing northeast when I saw the object I think this might have been the fireball.
