      <Description>The 3.5 meter telescope benefits the research faculty, graduate and undergraduate students, and public outreach programs of each member institution. Using innovative remote software, astronomers can operate and collect data from anywhere in the world. The telescope has a suite of cameras and spectrographs that serve a wide variety of scientific endeavors, resulting in more than 50 refereed science results being published each year. There is an active outreach program at the observatory and at member institutions. The 2.5 meter telescope, which operates the SDSSIII survey project, reached the midpoint of its 6 year survey. The project is a collaboration of more than 50 institutions and 600 astronomers. The primary foci of the survey this year were operations, Data Release 9, and collaboration science analyses. BOSS achieved 45% above the baseline rate for data acquisition. The APOGEE commissioning was completed and the first year of that survey yielded a world-leading data set. The survey produced new major scientific results, including international press releases.</Description>
