The IYA2009 Legacy - Roadmap to IYA2009's Living Heritage

2 February 2010

The document "The IYA2009 Legacy - Roadmap to IYA2009’s Living Heritage" is now available for download on this link (PDF format, 155.8 KB).

Introduction: The International Year of Astronomy 2009 was never foreseen to be a “one-off” event for one year, but a means to creating structures for collaboration, lasting self-sustaining activities and innovative concepts for the communication of astronomy. Within the IYA2009 project this “living heritage” goes under the name “IYA2009 Legacy”. This paper aims at giving, already in the last month of IYA2009, an overview of this legacy to the thousands of involved participants in IYA2009 at all levels – from SPoCs/project Chairs/stakeholders onwards. It will serve as a way to communicate the ideas for the future to everyone and will hopefully inspire nations and projects to find ways for the continuation of activities and collaborations that have long-term potential.

New SOFA software release includes geodetic/geocentric transformations

20 January 2010

SOFA (Standards of Fundamental Astronomy) is an IAU Service that operates under Division 1 (Fundamental Astronomy).  It has developed a set of software routines that implement official IAU algorithms for fundamental-astronomy computations. A new release of the software was made on 2009 December 31.  The total number of routines is 165, comprising 113 astronomy routines supported by 52 vector/matrix routines. The release incorporates the new IAU precession model
that came into force at the start of 2009. There is a "cookbook" that introduces the SOFA routines associated with precession-nutation and Earth rotation.

The most significant change since the previous release is the introduction of five new routines (available in both Fortran and C) to support transformations between geodetic and geocentric coordinates.

The Web address of the SOFA home page has changed, and is now:
