Bob Christy, Bram Dorreman, Russell Eberst, Kevin Fetter, Tim Luton, Rob Matson, Mike McCants, Greg Roberts, Patrick Schmeer, Brad Young, and I, contributed observations used to determine one or more of the following element sets.

On longer arcs, if I allow rate of decay to vary, I get ndot/2 ~0.00025 rev/d^2. For now, I choose to use shorter arcs, with zero rate of decay. Initial optical observations suggest that brightness may very strongly depend on phase, but I caution there is very little data. It may be worthwhile to make a special effort to measure brightness, as well as positions, to document any changes during the first days and weeks after launch.
