Draft LBT Operations Model LBT will be scheduled in partner blocks of 7-10 nights. Partners will send only experienced observing teams to the LBT. Observing teams will queue observe partners programs. Telescope reconfigurations, including AO, are permitted. Number/night is TBD. LBTO will provide daytime and nighttime technical support, LTO, and IQ Specialist.

Interventions and ToO with the LBT No policy currently in place. Discussed by Science Advisory Committee (SAC) in May Some partners may be interested in receiving notifications and acting on them. Consortium-wide agreements may be difficult to achieve. Models from similar partnerships may be helpful in formulating a LBTO policy.

Milestones for 2006 Aluminize DX primary. Retrofit SX cell and deploy DX cell with upgraded actuators, servo-electronics, and ventilation. Achieve Second Light. Commission LBC blue and red channels. Commission binocular operation (along with telescope operations sub-systems). Operational readiness review for seeing-limited imaging performance of the telescope. (Stretch goal:) Science Definition Time for LBC.

Plan for 2007 Delivery of 1st AO system in late Commissioning at SX straight-through Gregorian with NIR test camera. Installation and commissioning of MODS1. Commissioning of SX bent Gregorian with NIR test camera, initial AO testing on sky. Installation and commissioning of LUCIFER1 in seeing-limited mode. Installation and commissioning of PEPSI in single-fiber mode. Test and lab acceptance of AO system 2 in Arcetri, ship to mountain and install on DX. Continuing science with LBC red and blue.

Plan for 2008 AO commissioning with test camera on DX and LUCIFER1 on SX. Initial installation of LBTI. Initial installation of LINC-NIRVANA. Acceptance and installation of MODS2. Acceptance and installation of LUCIFER2. Continuing science with LBC, MODS1, LUCIFER1.
