Seemed to be very close. It's path seemed to parallel 19th street to the west. Very flat trajectory. At first I thought it was roman candle fireworks, but then it dawned on me that how would it be going parallel to the ground that fast and that far. In fact the color was almost identical to the green in a roman candle.
