It remained in the same general area for 35 minutes, moving up and down and sideways at irregular intervals. Observers occasionally saw showers of sparks or pale reddish particles. The sighting was reported at 9:30 p.m. and the object remained visible at 10:23 p.m. Two observers using binoculars of unknown power watched the event.
