I was on vacation in Europe during the first week of the third quarter of 1995. 
Thereafter, I attended the NATO Advanced Study Institute on Evolutionary 
Processes in Binary Stars in Cambridge, UK, from July 10 to 21. I presented
a poster on Observations of Close Binaries by Optical Long Baseline 
Interferometry.

Back in Washington, I worked for about 2 weeks on a paper on the radio quasar
0153+744. It will contain results from VLBI observations I obtained shortly 
before I left Bonn, and from VLA observations I obtained in 1991 and 1992.
I also reduced recent 1.3 cm VLBI data. I modeled the source with a precessing
beam, and finished a first draft of the paper which I submitted to colleagues
at the Max-Planck-Institute for Radioastronomy in Bonn. I have contacted
T. Cawthorne (UK) and R. Mutel (US) for a collaboration on this work. 

I received the second draft of the paper on Zeta Aurigae, a collaboration with
P. Bennett and G. Harper of JILA, Boulder, CO. I worked on it for a week 
and was visited by G. Harper for one day to talk about related issues.

My proposal to MERLIN to observe quasar 0836+710 (not mentioned in my report
for the third quarter of 1994) was accepted and the source was observed in
April of this year. The data will be sent to Washington, where I will make the
map and combine the data with VLA data I had obtained in 1991.

The first observations of four of our spectroscopic binaries with the McMath 
telescope on Kitt Peak (a collaboration with D. Peterson) were performed, and
I downloaded the data via anonymous ftp. On my request, G. Hennessy (USNO) 
installed the IRAF package on FORNAX, and I printed all related manuals. I 
have begun getting familiar with IRAF in order to reduce the spectra. I spent
about one week on a preliminary calibration of the data. I am planning to visit 
D. Peterson in New York for help with the final analysis.

Some work was done on data reduction software, CONSTRICTOR and STARBASE. With
the latter software I compiled a first version of a binary catalog for the
NPOI. I retrieved literature references for all 270 binaries from SIMBAD.

I continued to help with observations with the 26-inch refractor at USNO on
several nights. I will travel to Chiang Mai, Thailand, October 19 to November 4,
1995, in order to attend the Third Pacific Rim Conference on Recent Developments
in Binary Star Research. At this conference, I will give a talk on Long Baseline
Interferometry on Close Binaries.
