Regarding Greg's second UNID of Dec 17 UTC, I have fit three Molniya orbits of semi-synchronous mean motion, spanning
the typical range of inclination.

As Mike is fond of reminding, there are a jillion other possibilities (not all of them Molniya).
Intrinsic magnitude would be roughly 3 (1000 km, 90 deg phase angle). Since it was varying regularly, it could be a
rocket body, in which case its mean motion is likely to be 2.2 or greater.
It is probably worth a brief check to rule out a payload, allowing for mean-motion between ~2.004 and 2.01.
