From my location it was at an elevation just about 1/2 degree (one pinky width at arms length) above the ridge line that was below the fireball (ESE of us). I would have calculated the elevation angle better but my copy of Google Earth crashed.

The train was with the fireball and consisted of many yellow particles that were sparkling. I would estimate it was a few degrees
