This is just a heads up for folks off site, and for historical record of motivations: The commissioning team plans to restore IFO beam spot positions on Test Masses today.

The major reasons cited for "why"
    - RF build-ups are poor LHO aLOG 51175
    - ITMY spot position is on top of the point absorber LHO aLOG 51225
    - Lock acquisition vs. initial alignment has been a bear, e.g. from LHO aLOG 50952 to LHO aLOG 51112
    - New low-frequency glitching LHO aLOG 50973

So the plan is to remeasure the DARM loop sensing function (which has been stable and more physical in this position) one last time before the spot move (at ~9a local), then break the lock (at ~12-12:30p local), and move the spot positions at 2W.
