The 2008 NVO Summer School (to be held in Santa Fe, NM Sep 3-11) is now accepting applications at the NVOSS website

In this nine-day, hands-on program, participants will work with experienced NVO users and software specialists to become familiar with how to discover, access, visualize, and analyze data with the Virtual Observatory. Those attending will be introduced to VO tools and utilities by using them to accomplish a variety of research goals. Some of the research tasks that will be addressed include data mining, multiwavelength analysis, and temporal astronomy. In the latter part of the summer school, small teams will pursue their own VO-enabled projects.

Update: 06/17/08 Applications are now closed.

"The National Virtual Observatory: Tools and Techniques for Astronomical Research", published as an ASP Conference Series Volume No. 382, is now available from the ASP website: http://www.astrosociety.org/CS382.html. The price is just $35 for 750 pages of VO goodness and includes a software CD.

This volume is a collection of the NVO Summer School lectures and tutorials. It includes a complete set of software libraries and worked examples to guide the astronomer/software developer through the process of developing VO-enabled programs in a variety of programming languages and scripting environments. It is an essential guide for those interested in combining data from diverse and distributed astronomical data collections, for accessing large astronomical survey databases, and for making available to the research community one's own data collections and catalogs. In addition, the introductory material describes the origin of the Virtual Observatory and its potential role in astronomical research. Several chapters that describe research results obtained by participants in the NVO Summer Schools using VO tools and technologies are also included.

For those of you who got an iPhone or iPod Touch recently, a new web app called iPortal is available for browsing the VO Registry and Data services using only the native Safari browser. To get started, point your iPhone/iPod to http://iraf-nvo.noao.edu/iportal

A web page description with a test interface and screenshots is also available. This app provides access to hundreds of image and catalog services, and thousands of published journal tables, from a mobile device. Image displays and table scrolling use the native interfaces of the device.

See below for a full list of features.

A new set of tools for easily accessing Virtual Observatory data from the command-line (and thus scripting environments) is now available for testing. These tasks permit searching for VO resources and the query/access of image and catalog data from more that 15,000 sources. A key design point is the use of astronomer-friendly terms in specifying resources, general search capability (e.g. all X-ray image services), and a variety of output formats (default is CSV for easy manipulation by other tools).

The VO-CLI Project Home Page contains additional information, runnable examples, download instructions, as well as a guided tour of the software. These tools were developed as part of a larger VOClient project designed to provide a multi-language interface to VO data and services. They will be used in the upcoming IRAF NVO package but as host tools can be used from any environment. Examples of what you can do include: keyword searches to find relevant VO resources, process queries for lists of positions, easily find all HST data for a given object, or simply resolve and object name to its coordinates.

Since this is a testing release, feedback in the forums or comments is especially appreciated. Detailed examples of how to use the main data query/access task are shown in the main body of the story.

VO News Hot-wiring the Transient Universe: A Joint VOEvent & HTN Workshop will be held in Tucson, AZ on June 4-7, 2007. Registration for this workshop is now open at the conference web site: http://www.cacr.caltech.edu/hotwired/. This workshop aims to bring together developers and users of the HTN (Heterogeneous Telescope Network) Consortium and the VOEvent (transient alter notification protocol) Working Group to discuss technology, data fusion, and design of systems for the detectiona nd rapid follow-up of celestial transient events. Anybody interested in time domain or transient follow-up astronomy is encouraged to participate, not just members of the current VOEvent working group or HTN consortium. The workshop will take a global perspective from the point of view of the astronomical observing system at all apertures and wavelengths with both robotic and human mediated, real and virtual, telescopes and instruments.

Details and links (and a rather unique astronomy conference poster) available on the workshop website.

VO News Mark Taylor has announced the release of TOPCAT V2.1. This release features extensive support for the PLASTIC tool interoperability protocol and a new stacked line plot window. Further details on the project web page. TOPCAT is a tabular data viewer/editor and one of the only projects to survive the Starlink shutdown. I'm a big fan and recommend it for your FITS bintables every bit as much as VOTable xml.
