Judging by the size, per experts, the devices were of the tactical nuke class. (There's a couple of books on the subject; titles completely escape me at the moment.) The background radiation count also went up, but other than that, there was no proof that anyone had done anything - no point in announcing it.

If the titles or a link to the thread come to mind at some point- would you mind dropping me a ping? I have heard rumors of this- and my Googling on the subject has been less than spectacularly successful. :-)

In addition to an increase in background radiation, wouldn't satellite photos also show some sudden blank spots? Of course, this may be US classified info. Are there commercial satellite photos that one could access?
