Update: Scintillation and white outs proof of nuclear explosion and temperatures over 4000 C°
Scintillation is based on the distance from the blast. The farther you get away from the blast the less neutron exposure you get. CCD Cameras will detect scintillation but only at high levels. They are not sensitive to far field radiation patterns. All CCD cameras were too far away to be sensitive enough to show scintillation properly.
So you have to look at the white out in the centre of the photo. This is where the brightness is so great that it overloads the ccd pickup chip causing a clipping effect. The fact that the fireball was whited out or clipped indicates that the colour temperature was over 4,000 degrees C. Only achievable in a nuclear blast. The cameras auto gain circuit clips the video level for being too bright so you get a white out on the screen.
Just for analysis purposes I link here to an article from Veterans today. Veterans Today is an online publication of a group of US ex-army and veterans. This article was written by Ian Greenhalgh. This article is also from him.
If both articles pan out we are in a whole heap of trouble with the beginning of a nuclear war between China and the Western world. And Maybe China responded already
