Great idea.

You will be able to observe everything around you burning or being vitrified. Don't forget to glance down at your arms and legs so you can see the fat melting off your body and your body hair igniting as your skin is vaporized.

If you survive the immediate blast, please quickly find a way to have your observations recorded for future scientific study somewhere somehow (preferably in a way that will survive the nuclear firestorm that will likely burn all combustibles in the coming hours).

Realistically though, I don't believe actual nukes are going to happen.
