First Announcement
Workshop on
Defining the Data System for the
Frequency Agile Solar Radiotelescope (FASR)
University of Maryland
College Park, MD  USA
28-29 May, 2003
Online Pre-Registration Form

Dear Colleague:

You are invited to attend a 2-day workshop on the initial definition of the data system for the Frequency Agile Solar Radiotelescope (FASR).   FASR is currently in the early design stage, having been recommended for construction by the NRC's Astronomy and Astrophysics survey Committee and being ranked number 1 in the "small" (<$250M) catagory by the Solar and Space Physics Survey Committee.  When completed later in this decade, FASR will be the definitive instrument for ground-based solar radio astronomy, doing interferometry-based high-resolution imaging spectroscopy from ~0.1 to 24 GHz.  It will generate a raw data  stream of 10 Terabytes/day which must be converted promptly to fully-analyzed, high-level data products to meet the needs of FASR's multiple constituencies.  Users will include solar radio specialists, the solar physics community, the space weather community, operational forecasters and the public.

The purpose of this workshop is to bring together ~20-30 specialists representing a broad range of relevant disciplines including solar radio astronomy; the solar, space weather and forecasting communities; data analysis and data system design.  We will review the needs of end users, the new data products that FASR can generate,  the current FASR strawman hardware, the state of the art data-handling hardware and  software systems and will discuss various approaches to the FASR data system by which it can meet its goals.  Our objective is to come away with the outline of an optimum approach based on modern data systems and expectations for the future. From your perspective, it is an opportunity to share your unique insights, to become aware of the perspectives of your colleagues, and to make a fundamental contribution to the design of a state-of-the-art facility.  Many of the issues to be discussed also have relevance to other new facilities as well.

Althought the format of the workshop will include a number of invited talks to establish a common basis, the emphasis will be on lively discussion, in which the pros and cons of different approaches will be aired.  Specific topics will include:

        * Approaches to operations, data acquisition, storage and distribution
        * Real-time data products - prospects and requirements
        * The data analysis environment - technologies, programming languages,
                                        visualization, algorithms
        * Data accessibility by the broader community
        * Access and analysis by specialists

The workshop will be held at the University of Maryland just outside of Washington on May 28 and 29. Attachments include a signup form which can be edited and returned to, and some logistical details.  More information on FASR can be found at its website,


The University of Maryland offers an easily accessible locale.  The workshop will be held in an auditorium close to the Department of Astronomy.

The University of Maryland lies in the city of College Park some  8 miles north-east of the White House. The airport most  convenient to College Park is the Baltimore-Washington International airport (BWI), but the Washington area's other two airports,  Reagan National (DCA) and Washington Dulles (IAD), are both easily reached from College Park. Shuttle buses to hotels are available for roughly $20-$40, and Reagan National has a Metro stop that connects to College Park Metro, a short taxi ride away from the hotels. Parking cars on campus is always a sore point but we expect to be able to arrange parking.

Hotel accomodation is available in the city of College Park close to campus.Detailed information on lodging at local motels will be provided later.

Travel arrangements will be the responsibility of each participant.  We will provide detailed travel information at a later time.

There will be a specific website for the Workshop containing detailed travel information, lists of participants and so on.  For now, email  concerning the Workshop should be addressed to  You may also call Stephen White at:
