When observing a very bright fireball, when is the sonic boom typically perceived relative to the light flash?

Answer

After the visual event, as light travels faster than sound

The sonic boom is created by the shockwave generated as the object travels faster than sound, and this sound arrives on the ground after the visual light event because light travels much faster than sound.
