14 June 2009 (L+31, DOY 165)

At 10:53:17 UTC this morning the Herschel cryocover was commanded to open by manual commanding from the MOC at ESOC.

The command was executed nominally, there is telemetry indicating that the cover reached the open position, the shaking of the spacecraft caused by the opening was seen on the gyros and the phase separator, and the temperatures at L0 and L1 slightly changed.

All of this is consistent with what you would expect from a successful cryocover opening!
