AdLIGO Status as a Project• Large Projects at NSF are funded through MREF account (projects with total cost of more than ~10% of the annual division budget)
• A long list of possible MREF projects (23) are under discussion by all the directorates and the list changes with time.
• A shorter list of reviewed projects (11) are discussed annually with the NSB annually (a more stable list, but not prioritized)
• The Assistant Directors advise the Directorate (who decides) what and when to bring projects forward to NSB for consideration and approval
• Next big step is to obtain NSB approval and then inclusion in future MREF budgets to OMB (FY06?)

Conclusions S1 Analysis Complete. Five Papers approved for publication.
S2 Data Run was ~x10 better sensitivity and ~x4 more running time. Data analysis is near complete and we plan to present the results at GR-17 in Dublin in July. LSC Data Analysis Meeting this weekend
S3 Data Run: Three interferometers with extragalactic sensitivity. Analysis not yet underway
LIGO is shutdown to install L1 seismic mitigation
Advanced LIGO was proposed in Jan 03 and was well reviewed. It is now awaiting approval by the NSB.
Short term goals:» Commission Seismic Retrofit» Improve sensitivity and reliability to near design and initiate the
extended LIGO I search run.
