English: The relatively low-redshift quasar 1928+738 is located in a part of the sky that is always visible to HALCA, making the quasar well-suited to a detailed monitoring program of VSOP observations. Seven 5 GHz images are shown above, the first made in August 1997, the second in December 1997, and the last in September 2001. The horizontal spacing between images is proportional to the time between observations.
