Abstract :
During the program year ending on September 30, 2010, the Arecibo 305 m telescope was used for approximately 4,000 hours for astronomical observations with about 60% of the time devoted to large surveys primarily utilizing the ALFA 7-horn array. A structural problem limited telescope motion for most of the year but, as of early February 2011, has been repaired. A 12 m antenna was installed as a phase reference antenna to improve the efficiency of VLBI observations. Feasibility studies are underway for a 40-beam cooled phased array system as a successor to the ALFA system.
