Recent upgrades of the 10 micron interferometer have during 1997 been fully programmed, tested, and used. They provide improved tracking and stronger signals, and have been extensively used for new stellar measurements. Multiple shells around several stars have been found and analyzed, and movements or other changes with time are seen in the dust shells around some stars. Methods for compensating atmospheric fluctuations have been examined, and measurements of the vertical distribution of turbulence have been made with acoustic radar.
