[Stargate]

JoAnne,
	I'm using Spacetrack.org for my keps/TLE's so I would assume (yea, I
know:-) they are accurate. I will check the HST since it should not have
changed much.

Thanks,

It may depend on which keplerian elements you're using.  ISS boosted its
orbit up an additional ~5 miles or so this week.  If you are using pre-boost
elements then ISS will appear later than predicted because of the higher
orbit.
