>I saw a video where it glowed golden across the entire landscape for some seconds (and even then the first 2 seconds of the video was missing, the fireball was allready in the air), and you could see every blade of grass from the cameraman to the explosion which happened seemingly 2.5 miles away beyond a field, treeline 1, houses, treeline 2, water, land with treeline 3, more water, more land with treeline 4. The glow stayed for a few seconds. It was golden color like a morning sun. Then it blinked out abruptly. The blast wave hit the cameraman 7 seconds in and he stumbled.
