    I didn't expect that SpaceTrack would release any TLEs for USA-193 debris, but I thought that we could figure out *how many* debris objects might have been cataloged by the gap in numbers between 32499 (the last one added before the USA-193 shoot-down) and the next number in the list.
    But today SpaceTrack added the two objects from the KIZUNA/H-IIA launch, and they are the next two numbers in sequence: 32500 & 32501.
    Why is it that classified objects get numbers, but just don't get published with a "U" (i.e. we see the gap in numbers), but USA-193 debris have no "place holder" numbers?
    Or could it be that they haven't observed any debris? (I note that I haven't seen any posts on SeeSat-L with any visual reports or timings of debris.)
