Hmmm, not sure what I think about the best way to represent proper  
motion.

Time series are also not meant to address the expression of orbital  
elements.  STC should serve nicely for this.

That said, I agree with the underlying point that "light curve"  
implies a too narrow interpretation.  Raw astrometry might be  
expressed as a sequence of follow-up packets, or might be expressed as  
"tabular" data in a TimeSeries element.  The former is trivially  
supported in all cases.  The latter, as Andrew says, is not a light  
curve but is still a series of measurements versus time.
