[Isocops] Fwd: RE: Ephemeris check failure

[Mark Tapley]

Lisa,
	as Chelle points out, we probably know why the uncertainty is 
higher right now, and we barely fail, so I suspect this is kind of a 
dry-run, but at your convenience (low priority!) could we get a 
variance print-out as we discussed covering out to March 5?

Large Asteroids headed toward planets
inhabited by beings that don't have
technology adequate to stop them:

				Think of it as Evolution in Fast-Forward.
