I already blogged about how our small bunch of dedicated amateur trackers located and followed this classified satellite within hours after launch (I myself observed it on it's second revolution, 3 hours after launch). Since then, we have kept following it, documenting a number of orbital manoeuvres.
On the evening of August 30 Russell Eberst in Scotland and Cees Bassa in the Netherlands noted the satellite was notably late on the predictions, suggesting a manoeuvre. Observations by several observers (communicated on the SeeSat list) analyzed by Ted Molczan in Canada show it manoeuvred on August 30 near 9:15 UTC from a 252 x 996 km into a 254 x 1002 km orbit.
A day later, on August 31 near 18:30 UTC, it manoeuvered again, to an approximately 259 x 1007 km orbit. It will probably manoeuvre more in the following days.
The satellite now has the Cospar code 2013-043A, and by looking at the omissions in the SSC catalogue numbering we know it has SSC ('NORAD') number 39232.
