I passed the OrbView-2 control room on my way to the office this 
morning. (I work for Orbcomm, which is, for the moment, based in the 
main Orbital building in Dulles, VA). 

On the window was a sheet of paper listing all of the satellite burns 
since launch. 

As of 1400 UTC today morning there have been 25 burns since launch, the 
most recent (burn #25) at 0221 UTC today (8/28). There were 5 burns 
(20-24) on Wednesday, August 27. 

The mean orbit is now 647x 657, with the target height of 705 km. 

I'll try and get a copy of the history when they've completed all of the 
maneuvers. 

Enjoy!
