According to Mike McCants' int3 propagator, the orbit is fairly stable for the short term. Barring further manoeuvres, it will reach 42.4 E about 2009 Aug 04 UTC, remain there about three weeks, and then drift back to its present position by about 2009 Oct 22 UTC. It would require a small manoeuvre to prevent it drifting to 58 E by the end of the year. My guess is that its intended range of operation is between about 43 E and 50 E.
