As it was not yet dark enough at 8:30 pm, the only references I had to determine the trajectory were the brighter constellations like Big and Littel Dipper and Cassiopeia. The bolide was quite slow with an estimated apparant speed of approx. 15km/s. The duration of the luminous trail was approx. 3 seconds.
