This report summarizes the activities of the United States Naval Observatory Analysis Center for Source Structure for calendar year 2009. VLBA RDV experiments RDV71 and RDV73 were calibrated and imaged. Images from these two experiments, together with images from RDV25 were added to the USNO Radio Reference Frame Image Database. VLBA high frequency (K/Q-band) experiment BL151a was calibrated and imaged. A Southern Hemisphere imaging and astrometry program for maintenance of the ICRF continued. Activities planned for the year 2010 include continued imaging of ICRF sources at standard and higher frequencies and continued analysis of source structure and its variation.
