I live in Edgewater and was on the River path that night, on the south side of the river, walking with my wife. I too saw something odd to the south south west. I at first thought it was venus, untill I located venus off about 15 degrees further south. I then observed the object was in motion (I had been walking and may have missed motion at first as I was sure it was just venus). It then went up, down, to the west a bit, and then zipped off to the east with rapid acceleration moving low on the horizon and passing below venus. I lost sight of it behind the trees and buildings at that point. My wife and I then went home, missing the lighting of the river, so I can say this all happoned about 5 or 10 min before they lit the river (St. Joe, east race) which was lit at about 10:20pm EST.
