Question Hubble Solar array jettison

[agentgonzo]

On STS 61 (Hubble servicing mission 1), the astronauts jettisoned one of the solar arrays after servicing (the second was returned to earth in the Shuttle for analysis). Does anyone know how long it took to deorbit from its ~600km orbit?

This is in german, but maybe you can read it:

Right is the liftime of the satellit in years and and on the bottom axis the heigh of the orbit.
