In the first quarter of 1992, I spent most of my time reducing 
astrometry data from the MKIII interferometer and observing with this 
instrument on Mt Wilson.
After further modifications of the astrometry software, I reduced the 
data from July, August, and September of 1991. The determination of 
stellar positions from these data, however, is not yet completed, due to 
continuing problems with insufficient accuracy of the measured delays 
(which provide the basis for position measurements). The data from 
August will provide crucial tests of the accuracy of the positions, 
since in this session, each North-South/East-South baseline combination 
was observed twice, so that independent data sets can be formed and the 
results compared to one another. 
During two visits on Mt Wilson, each lasting two weeks, I tried to 
gather more data for the binary program. The weather, however, allowed 
observations only during a few nights with mediocre seeing conditions. 
In addition, equipment failure (the tape drive) caused loss of 
observation time. A demonstration of the instrument to a team from CNN 
(Cable News Network) on February 3 was successful. 
I spent two weeks preparing a poster presention for the IAU 
colloquium "Complementary Approaches to Double & Multiple Star
Research", which I will attend in April (in Atlanta). This included
writing additional binary software for the purpose of error estimation
and display of the results.
Finally, a hardware and software overhaul of my PC was completed.
