At the beginning of the third quarter of 1994, I continued my work on 
CHAMELEON, the visibility averaging and calibration program for the 
NPOI. This program was essentially finished by the end of July and I 
used it to re-calibrate some Mark III data of binaries. Due to delays 
with the dedication of the NPOI, CHAMELEON has not been fully tested 
yet. 

From July 30 to August 13 I went on vacation in Germany. From August 14 
to 23, I went to the Hague and attended the General Assembly of the IAU 
and Symposium 166 on "Astrophysical Objectives of sub-milliarsecond 
astrometry". I gave a contributed talk on "Single and double star 
astrometry with the Mark III interferometer". One of the results from 
the Mark III which was most recognized by the audience and speakers from 
the HIPPARCOS team is the agreement of the positions of twelve stars 
that we observed for many years with the HIPPARCOS results at a level of 
22 mas. On another issue, Tom Armstrong and I have convinced people that 
a renewed effort in determining spectroscopic elements of binaries is 
necessary to match the accuracy of orbital elements obtained with 
optical interferometers in order to determine high accuracy masses and 
luminosities of stars. I also became member of Commission 26 (binaries). 

After returning from the Hague, I resumed working on my paper on small 
angular scale binaries which I had started during the first quarter of 
this year. I finalized the reduction of two more binaries, which I then 
added to the paper. The orbit of one of them (93 Leonis) is new. I also 
determined the orbit for Zeta Aurigae for which our previous attempts 
had failed. The paper, now containing 8 binaries, is close to being 
finished and I hope to submit it to AJ the next quarter.
