Welcome to IAU Commission 40 for Radio Astronomy. Commission 40 is part of IAU Division B for Facilities, Technologies and Data Science.

Commission 40 brings together scientists and engineers who carry out observational and theoretical research in radio astronomy and who develop and operate the ground and space-based radio astronomy facilities and instrumentation that are used to explore the universe at radio wavelengths.

IAU Commission 40 for Radio Astronomy was first established in 1948. In 1997 it became the only Commission in Division X, and in 2012 it became part of the new Division B. As at June 2014 this Commission has approximately 1140 members from 49 countries. 3:30 PM 20/01/2015

IAU Commission Reform: Updated 20 January 2015

In June 2014 the IAU issued an announcement on a plan for reforming the IAU Commissions. This plan includes a call for proposals and the selection of new Commissions. All current Commissions will cease and, following a selection process, new Commissions will begin at the IAU General Assembly in August 2015.

Following the call for proposals, the IAU received 54 Letters of Intent for Commissions. These included a Letter of Intent for a 'new' Commission for Radio Astronomy submitted by Commission 40. To indicate community interest, IAU members were asked to cast a vote for their preferences.

We thank all those who supported this process by casting votes and appreciate the strong support shown for the letter of intent for a Commission for Radio Astronomy (NC-34). This received the highest number of votes overall.

The next stage in this process is the submission of full proposals by end-January 2015. The IAU expects to announce the new Commissions around April 2015.
