Subaru Strategic Program FMOS SSP: FastSound project interim review  OK to continuation of the project HSC SSP refereeing – Proposal: “Wide-field imaging with Hyper Suprime-Cam: Cosmology and Galaxy Evolution” PI: Satoshi Miyazaki – Science review (3/28 by TAC)  OK – Organization review (4/23 by SAC)  OK – Final review (4/23 by SAC)  Acctepted years (including weather factor) – Start from S14A Request from SEEDS project (HiCIAO SSP) – Additional 30 nights ← telescope troubles, weather condition, and new science themes – Accepted only 2 nights lost by telescope troubles. 2014/1/21Subaru UM 20137

Constraint on time allocation of SSP Total nights : up to 300 nights per 1 SSP Duration: up to 5 years per 1 SSP SSP nights per year: up to 60 nights in total – Up to 25% of the machine time per semester 2014/1/21Subaru UM 20138

Discussed items on open use, operation, etc. (except for SSP) HSC open use timeline HSC filter acceptance policy – Defined the procedure of acceptance of narrow-band filters Status of Progress of PFS project Instrument decommission – Possibility of decommission of FMOS in 2015 for smooth installation of PFS Time-exchange with Gemini Queue-mode observation Open use observer acceptance policy 2014/1/21Subaru UM 20139

International relations Euclid-HSC collaboration proposed by Euclid team – Should consider this item with relationship with other big projects: WFIRST, LSST  “Collaboration of Subaru and big galaxy survey projects in 2020s” workshop (Jan ) GLAO Science Workshop – In Hokkaido, June Cooperation with east Asian countries East Asian Observatory concept and Pan Pacific Observatory concept Subaru data analysis school in Korea 2014/1/21Subaru UM

Discussion items in this year How to collaborate with the next generation big projects including Euclid, WFIRST and LSST using Subaru Extension of time-exchange program International cooperation on Subaru operation (EAO, MKO, and PPO) 2014/1/21Subaru UM
