Actually you can see several more flashes after that.

[libtechsk8er]

Maybe it's the camera?

[CampKohler]

If the explosion occurs at 00:13, what is the flash that occurs at 00:16?

[libtechsk8er]

Good question, I never noticed that.

Is this the ONLY unedited test footage available to the public? Lots of nuke footage exist but ONLY this one I have found that has the correct timing of the sound. Are there ANY other unedited test footage like this from nuke tests?

[BenHutchinson1]

Camera switching between different light sensitivities due to the different light levels after the explosion, from VERY bright, all the way to black. When the camera switches between exposure settings it seems to glitch and make it slightly brighter for a fraction of a second.

@CampKohler thats a typical phenomenon. After the fission (seen as first bright light) a huge fireball builds, witch is less brighter than the fission reaction. In further process the outer areas of this fireball vanquish and open view to the much brighter core (the second bright light). Soon later the whole fireball cooles of and very view light is emitted.

@nukewarfare2 Am I right in thinking the double flash occurs at a much earlier stage than what we see here? I thing we have a fully mature fireball here that has already gone to mushroom cloud when the second "flash" happens.

The more I look the more I think it is camera aperture being adjusted, as others suggest.

[jeselmira2]

@CampKohler I'd guess atmospheric effects are blocking some of the light for a time, like Wilson cloud formation (Nevada is pretty dry, though) or something similar? I'd say it's that or camera issues.

I think we can say that there is nothing to cause a "flair up" like you get in many conventional explosions, where air, fuel, and temperature distribution can cause uneven burns.

@CampKohler its the camera refocusing to adjust to the light. nothing out of the ordinary.

@BenHutchinson1 this nuclear explosion was done in the morning and was the first one done live on national TV. The today show on nbc ran this live on the air.

[cowpalace95]

Is that sound at the start the noise of the air compressing and heating up or is it something to do with the camera or something else

[nukeseeker]

That flash is the camera being switched between settings. By the way that bang was tremendous.
