TUESDAY MAINTENANCE PLAN

Attached is the whiteboard list of tomorrow's scheduled tuesday maintenance activites.  We'll start with RCG upgrade and work through various other invasive around-site tasks. 

Here are the list of tomorrow's maintenance day tasks organized as we intend to execute them chronologically, and prioritized such that the tasks with the most global impact on the IFO are done first (such that we have the most time to recover from them). As with last Tuesday (LHO aLOG 19600), all tasks, associated estimated times for completion, and responsible persons (or "task manager") will be added to the reservation system when they are *actually happening*, and removed after the task manager has checked in with the operator and confirmed completion. PLEASE PAY ATTENTION TO THE RESERVATION SYSTEM (to help, we're going to put it on the big projector during maintenance). 

As always, please keep the operators informed of your activities as accurately as possible / reasonable throughout the maintenance day so the reservation list can be adjusted accordingly and remain accurate. We appreciate your cooperation!
