The Advanced Technology Solar Telescope SWG Meeting 9

The Advanced Technology Solar Telescope SWG Meeting 9 -11 September 2009 NSO Operations of the ATST

Operation Assumptions • ATST will be oversubscribed and available observing hours must be maximized. • Both PI-mode (on site) and queue-mode (service mode, for either PI or community) observing will be supported. • ATST will be scheduled together with spacebased observations frequently (priority? ). • ATST instrumentation and data analysis will require strong scientific support. • NSO will restructure its organization to support ATST operations 10/26/2020 2

Operation Assumptions • NSO will integrate ATST data archiving into its data center • ATST will dynamically respond to changing solar conditions on timescales of hours to days • ATST Instrumentation development will be an ongoing program. • Some instrument maintenance and instrument change over will occur at night. • ATST will support remote observations, which is defined as telescope status and acquisition, telescope status availability for remote collaborators. • ATST will support night-time observations on a case-by-case basis only. 10/26/2020 3

Operating Locations • Summit Facility – telescope and support structures on the summit • Maui-base – administrative and technical support services, data handling at the mountain base • NSO Headquarters – data center, instrumentation program, business services 10/26/2020 4

Transition from Construction • Integration, Testing, and Commissioning (IT&C) • Begin ramp up of operations personnel to support IT&C • Personnel Training • Science Verification – Instruments – Calibration of control systems • Acceptance Matrix (SPEC-0038) 10/26/2020 5

Observing Modes • Queue-Mode (service mode) – These are PI proposals or community programs that require specific environmental or solar conditions. They are placed in a queue and executed when the specific conditions are available. The proposal can be executed without direct participation by the PI. • PI-Mode (visitor mode) – requires direct or remote participation by the PI • Engineering Mode – time allocated for maintenance, instrument development and commissioning 10/26/2020 7

Observing Programs • Campaign Programs – These are queue-mode (service) or PI-mode observations collected by visiting or NSO scientists in collaboration with other space and ground facilities in campaigns • Community Programs – Collection of standard datasets of general interest. These could include a standard observation of a canonical active region, a series of observations of an active region during its entire transit across the disk, or the collection a statistical sample of observations of a specific solar feature. They would be conducted in consultation with the community and would allow for “generic” data sets that can be used by many different people (similar to a nighttime survey program). 10/26/2020 8

Telescope Allocations • Proposal Period – 6 months • Instrument Calculators (for PIs, for TAC and Operators) • Common submission software • ATST Support Scientists – Instruments – WFC – Data • Proposals screened for technical feasibility 10/26/2020 9

Proposals • Program goals and target details. • Specific instrument configurations, including any changes during the observations • Quality assurance recommendations. This may incorporate S/N requests for identification of specific features (e. g. weak magnetic fields, spicules) and should include configuration of the “on-line” data processing system (e. g. image addition subtraction, speckle). 10/26/2020 11

ATST Data • Open data policy – PI proprietary period? – Limited proprietary period for thesis data and instrument development? • Permanent archive of raw data and meta data (calibrations, status, etc. ) • Data Processing – Instr. builder & community codes • Data Archive for processed data • Data Access – Virtual Observatory – FTP – Media 10/26/2020 12

Life Cycle Cost • Provide forefront solar data for ~44 years. • Built in flexibility and careful attention to future upgrade options ensure a robust growth path • Estimating a cost of $14 M for ongoing ATST operations gives a total cost between $420 M and $560 M in 2009 dollars. • Combined with the construction cost this gives a life cycle cost of approximately $850 M. 10/26/2020 23
