Radio Astronomy

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.

Special Announcements

Just a reminder ... there will be NO URSI National Radio Science Meeting in Boulder this coming January! We are finally back to the normal cycle of skipping the Boulder meeting during the years when the North Americian Radio Science meeting convenes. The next Boulder meeting will take place in January 2016.

The dates for the 2014 NRSM are URSI International is planning a new triennial conference. The URSI Atlantic Radio Science Conference will take place at the ExpoMeloneras Convention Centre, Gran Canaria, Carany Islands May 18-22, 2015. Commission J will hold sessions at this event. The abstract deadline is December 15th, 2014! For more information see

The USNC/CNC - URSI North American Radio Science Meeting (NARSM) will be held on July 19-25, 2015 in Vancouver, BC Canada in conjunction with the IEEE International Symposium on Antennas and Propogation. The paper submission deadline is January 15, 2015! For more information see

Links to the Radio Science Bulletin (RSB) here for March 2014 and June 2014. Several very interesting articles have appeared there over the past several months including one by Jaap Baars on the history of flux density calibration. Please consider contributing an article to RSB. I am currently writing an article about project PAPER.

On a personal note, I have been remiss in publishing the USNC-URSI-J Newsletter over the past several months (since March!) and for this I sincerely apologize. I also wish to express my sincere thanks to Ken Kellermann who represented USNC-URSI-J at the URSI GASS this summer in my absence. While my tenure as Chair of USNC-URSI-J comes to a close next month, I am gratful to have been elected Vice-Chair of URSI International Commission J so that I may continue to serve our fine organization. Thank you for your support.

Contributions of newsworthy items that are of interest to the membership are always welcome.

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.
