The best fireball of the night was not a Sentinel systemcapture but my forward scatter array and video camera caught it in the far distance.
It happened over southern New Mexico and appears in the movies below at screen bottom.
Sonic Movie 1: Ashcraft's dual frequency forward scatter system; video and stereo sound:
Note that the reflection flares as the visual fireball flares. Good sonic definition. Head echo only.
