Remarks
Bright white broad at the head and tapering to the rear. Bright enough to cast shadows and reflect the blue light off objects. At first I thought it was vehicle headlights on a nearby road.
Terminal flash
Observation
Unknown
Remarks
Super bright blue light like a sun lamp. Bright enough to cast shadows and reflect it\'s light on facing objects on the ground. The object was sort of low on the southern horizon and my line of sight was partially through pine trees but there was enough clear spots to really grab my attention. This ball was about 10 times the size of Venus and of similar color but much brighter than Venus is currently. Venus was not visible to me at this time of night.
