Commission J activities are concerned with observation and interpretation of all radio emissions and reflections from celestial objects. Emphasis is placed on the promotion of technical means for making radio-astronomical observations and data analysis as well as the support of activities to protect radio-astronomical observations from harmful interference.

I am pleased to announce that Dr. Jim Moran (Harvard-Smithsonian Center for Astrophysics) will give the Commission J "Lessons from History" lecture at the 2014 National Radio Science Meeting in Boulder!
The dates for the 2014 NRSM are Wednesday, January 8th through Friday, January 10th. Unfortunately, there will be some overlap with the 223rd AAS meeting scheduled for January 5th through January 9th in National Harbor, MD. More details are given below.
We need your contributions to the new section of our website: "Membership Activities." This section is devoted to brief news items from the membership of USNC-URSI-J. Have you recently returned from an adventure to a remote field site? Have some interesting results to share? Please send the Chair, Rich Bradley, a brief description and a photo or two as well as a link to a website for further information, if needed.
Many of the Commission J presentations are now available here at our Commission J website. These are open-access to everyone. If you would like your presentation included, please send a PDF copy to either your Session Chair or me. Of course, posting is completely voluntary. We will post exactly what is sent in reply to the request (not the original). Hence, at your discretion, the presentation may be slightly modified from that presented at the conference to remove sensitive information. In addition, sending a copy to us for posting implies that we have permission from all of the authors to post the presentation. It is your responsibility to obtain permission from all of the authors. If you would also like to share the PPTX or other version (perhaps containing animations, etc.) please provide a hyperlink to a copy in that format that is located elsewhere.
Contributions of newsworthy items that are of interest to the membership are always welcome.

I have completed a book with the working title "International Radio
Telescope Projects - A life among their designers, builders and
users". It contains "documentary stories" of the projects I have been
intimately involved in.

Membership Nominations
Please consider nominating someone for membership in USNC-URSI Commission J. The required qualifications for membership in the Commission are technical competence and interest in the activities of URSI. Students are encouraged to become involved - they can be nominated for non-voting Associate Membership. This is a three year term that can be renewed once for a total of six years. Guidelines for membership and the on-line nomination form can be found at the usnc-ursi membership nomination web page. The membership will vote on the nominees during the Boulder Commission J Business Meetings in January.Reference Documents
Radio Science, a fully refereed journal published by the American Geophysical Union (AGU) and cosponsored by URSI, carries original scientific contributions on all aspects of electromagnetic phenomena related to physical problems. These contributions can include propagation through and interaction of electromagnetic waves with geophysical media, biological media, plasmas, and man-made structures. Coverage includes, but is not limited to, the application of electromagnetic techniques to radio astronomy, the ionosphere, remote sensing of the Earth and its environment, telecommunications, and signals and systems. All frequencies (including optical) are considered.
