Cees Bassa, Derek Breit, Russell Eberst, Kevin Fetter, Marco Langbroek, Alberto Rango, Scott Tilley, Brad Young, and I contributed observations used to update at least one of the following element sets. The ORS 1 elset employs a mean mean-motion to account for the object's frequent manoeuvres to maintain altitude against drag. Over the 48 day span, the prediction time error typically is under 20 s; worst case is 32 s. It would be prudent to allow for at least 1 min prediction time uncertainty if the object has not been observed for more than two weeks.
