There was a barely visible \'smokey\' trail to the point of the EXPLOSION circle which was initially bright white (as bright as a full moon), made absolutely no sound and disappeared leaving a cloudy circle for ~ 1 second.
The track was nearly as wide as a pencil eraser held at arms length; the explosion circle was as big as a quarter held at arms length.
I saw no debris falling from the track and there was no visible trails following the explosion.
Terminal flash
Observation
Yes
Remarks
The flash was \'brilliant\', easily as bright as a full moon. The flash ball produced was very close to a circle (not elongated). The color across the circle varied from bright white towards the center to a yellow-white towards the edge. The size of the circle was that of a quarter held at arms length. The edge of the circle was jagged like a fine saw blade.
