The Twelfth Synthesis Imaging Workshop will be held at the NRAO and the New Mexico Institute of Mining and Technology in Socorro, NM, on June 8-15, 2010. In addition to introductory lectures on radio interferometry, advanced topics will cover a selection of new synthesis instruments, including the Atacama Large Millimeter Array (ALMA), the Expanded VLA (EVLA) and the Long Wavelength Array. The workshop will also feature two days of hands-on data reduction tutorials, and tours of the EVLA and the Science Operations Center. Attendance at the Synthesis Imaging Workshop will be limited to 150 people. See for more information on scheduled lectures and events. If you are interested in receiving more information about the workshop, please pre-register at the same web page. Full registration will open February 1st, and will be on a first-come-first-served basis. There will be a registration fee of $200, which includes a copy of ASP Conf. Ser. Vol. 180, "Synthesis Imaging in Radio Astronomy II."

Information for participants outside the US: it is our understanding of current US policy that attending a scientific workshop in the US should only require a visitor visa. Should you find you need a letter of invitation, please contact Amy Mioduszewski. Due to processing delays we strongly encourage you to start paperwork early.

The Synthesis Imaging Workshop is sponsored by the National Radio Astronomy Observatory, the New Mexico Institute of Mining and Technology, and the University of New Mexico.
